60 Poison Puns That Are Toxically Funny

Poison is one of those topics where the puns practically write themselves and yet somehow I still manage to mess half of them up. I’ve been sitting on this list for like two weeks because I kept finding more angles, mushrooms, snakes, arsenic, the whole apothecary of wordplay. Some of these are genuinely clever. Some of them are crimes against comedy. You’re getting all of them.

1. The opener

My puns are deadly serious.

(That one’s free. It’s the amuse-bouche of poison humor. We’re warming up.)

2. A personal favorite

I told my friend I was writing sixty poison puns and she said, “Why?” And I said, “Because I have a potion-tial for making bad jokes.” She blocked me for nine minutes. Worth it. This is genuinely one of the puns I’m most proud of because “potential” and “potion” line up so cleanly. Sometimes wordplay just hands you a gift.

3.

Why is that snake so friendly? Because it’s venom-in-us!

4.

There’s always mushroom for improvement in my pun writing.

5. The cluster round

• These puns are berry good, but also berry dangerous.
• I’m apple-solutely sure that one made you groan. (Snow White walked so I could run.)
• Honestly, the whole poisonous-plants-as-puns genre is low-hanging fruit. Nightshade I say more?

6.

Drop-dead gorgeous.

That’s it. That’s the pun. It’s also a viable Instagram caption if you’re posting a selfie in all black, which I respect.

7.

I need an anti-dote to all this negativity. Just a small prescription of good vibes and terrible wordplay.

8.

What do you call a poison expert who’s also a musician? A toxic-ologist with great composition skills.

9. I’m sorry in advance

These toxin puns are really taxing my brain.

Yeah. I know. That one’s a stretch and a half. Moving on.

10.

His corrosive wit could eat through steel. I’ve met people like that. They’re fun at parties for exactly twelve minutes and then everyone finds somewhere else to be.

11.

He was skull-king around the lab, looking for antidotes.

12. Caption energy

Toxic but make it fashion. ☠️

13.

“How was the potion?”
“It had its ups and downs. Mostly downs. I’m in the hospital.”

14.

What do you call a witch’s beautiful concoction? Brew-tiful.

Honestly that one’s kinda cute. I’d put it on a mug.

15.

Just a sip-erior pun for you.

16. One of the good ones

A chemist and a bartender walk into a room. The chemist says “I’ll have H₂O.” The bartender says “I’ll have H₂O too.” The bartender dies. This isn’t technically my pun, it’s THE poison chemistry joke, but I’m including it because if you haven’t heard it, you deserve to, and if you have heard it, you know it slaps every single time. The hydrogen peroxide reveal is just *chef’s kiss*.

17.

Arsenic and Old Lace? More like Arsenic and Old Laughs. Okay this one is terrible. I’m leaving it in as a monument to my failures.

18.

I tried to make a pun about cyanide but it was bitter work.

(Cyanide famously has a bitter almond smell. This is both a pun and a fun fact. You’re welcome.)

19.

That snake has a lot of charm, but it’s still a snake-y character.

20. The tangent

Can we talk about how poison is like the most dramatic way to do anything in literature? Nobody in a mystery novel just gets a normal illness. It’s always “a rare alkaloid extracted from the Calabar bean.” Agatha Christie really made toxicology sexy and I think about that a lot. Anyway,

21.

Why did the hemlock break up with the nightshade? The relationship was too toxic.

22.

I was gonna tell a ricin pun but I didn’t want to castor bad light on legumes.

THIS ONE. I’m genuinely proud of this one. Ricin comes from castor beans. If you knew that already, we’re friends now. If you didn’t, look it up, it’s wild, the same plant that gives us castor oil can also, you know, do the other thing.

23.

Strychnine? I hardly know nine!

Garbage. Absolute garbage. I’m not even going to defend it.

24.

My spider sense is tingling, I think a bad pun is coming.

25. Rapid fire

• Venom? I barely know ’em.
• That joke was so bad it should come with a warning label.
• I’ve been bitten by the pun bug. It might’ve been venomous.

26.

What’s a poisoner’s favorite card game? Arsenic rummy. No wait, Toxic Hold ‘Em? I don’t actually have a punchline for this one that works. Sometimes you just gotta admit the setup led nowhere. Let’s move on.

27.

Don’t contaminate the conversation with those toxic remarks!

28. Niche alert

I asked the pharmacologist about aconitine and she said, “Monkshood really be careful with that.” If you know, you know. Aconitine comes from monkshood (also called wolfsbane). This pun is for approximately eleven people and I love all of them.

29.

These poison puns are the bane of my existence. Wolfsbane, specifically.

30.

I’m going to ingest this information, in jest, of course.

31.

“Doctor, I think I’ve been poisoned!”
“What did you take?”
“Constructive criticism.”
“That’s not, “
“IT’S KILLING ME.”

32. Instagram-ready

Poison ivy? I prefer poison I-vy League. 🎓☠️

Would I post this? Yes. Would it get likes? No. Do I care? Also no.

33.

My love life is like a poison dart frog, colorful, exciting, and everyone knows to stay away.

34.

It was a fatal attraction to the pun convention.

35. Another one I know is bad

I’m feeling a bit toxic today. I’ve been telling too many poison jokes.

This is the kind of pun that technically works but has the comedic energy of a damp napkin. Including it anyway because quantity has a quality all its own.

36.

What did the belladonna say to the hemlock? “We should hang out more, people are dying to meet us.”

37.

My cooking’s not poisonous. It’s just… lethally seasoned.

38. The Borgia special

Tbh if I lived in Renaissance Italy I would simply not accept drinks from anyone named Borgia. The Borgias were basically the original “this meeting could’ve been an email” people except the email was cantarella and the meeting was your funeral. Anyway: the Borgias really knew how to host a killer party.

39.

Why did the toxicologist win every argument? She always had a deadly comeback.

40.

Some puns are slow-acting. This one’s a sleeper agent.

41.

Curare you glad I didn’t say banana?

Ngl that’s the worst one on this list and the competition was already fierce. Curare is a paralytic poison. The pun is unforgivable. We’re moving on.

42. Mini-cluster

• Cyanide: putting the “die” in diet since forever.
• Mercury poisoning? That’s mad as a hatter. (Literally, look up hatters and mercury. Victorian England was unhinged.)
• Lead poisoning is plumb awful.

43.

What do you call a snake that works in construction? A boa constructor. Wait, that’s not even a poison pun. That’s just a snake pun. I’m losing the plot.

44.

She had a venomous tongue but honestly? Great debate skills.

45.

The poison pen letter was write on target.

46. Text you’d send at 1am

“just found out about thallium poisoning. they used to call it inheritance powder. history is UNHINGED. anyway goodnight”

That’s not really a pun but it’s the vibe of someone who’s been researching poison puns for too long. Which is me. I am that person.

47.

I tried to write a pun about atropine but my pupils were too dilated to see the keyboard.

Okay this one’s actually clever if you know your pharmacology. Atropine causes pupil dilation, it’s literally used in eye exams. The fact that it also comes from deadly nightshade is just the cherry on this very poisonous sundae.

48.

Don’t let these puns poison your mood!

49.

Why did the chemist break up with the biologist? Too much chemistry, not enough biology. Also he kept leaving unlabeled vials everywhere and that’s a SAFETY HAZARD, Derek.

50. The big five-oh

We’re fifty puns deep. If you’re still reading, you’re either genuinely enjoying this or you’re a completionist with a problem. Either way I respect you. Here’s your reward:

What’s a poisoner’s favorite Shakespeare play? Othello? No. Romeo and Juliet? Closer. The answer is Hamlet, because the whole ending is basically a poison speedrun.

51.

Iocane powder? Inconceivable!

If you don’t get this reference we can’t be friends. (Princess Bride. Go watch it. I’ll wait.)

52.

That scorpion really knows how to make a point. Several, actually.

53.

I asked the dart frog how it stays so vibrant. It said, “Clean living and a killer personality.”

54. Okay this one I love

Socrates walks into a bar. Bartender says, “What’ll you have?” Socrates says, “I’ll have what’s hemlock-ing good.” He did not survive the evening. I know Socrates puns are overdone but I don’t care. The man drank poison rather than stop asking annoying questions. He’s the patron saint of this blog.

55.

My ex was like arsenic, tasteless, odorless, and slowly ruining my life.

Caption material. Send that to your group chat. I dare you.

56.

What’s a toadstool’s favorite music genre? Spore-ison. Okay that doesn’t even make sense. I tried to mash “spore” and “poison” and it went nowhere. This is what happens at pun #56.

57.

“Are these puns safe?”
“They’re non-toxic.”
“That’s what they all say.”

58.

The snake oil salesman was just winging it. Or fanging it, I guess.

59. Second-to-last and I’m running on fumes

You know what the problem with poison puns is? They never get old. Because nothing that’s been poisoned gets old. That’s… that’s the whole joke. It’s morbid. I’m tired.

60.

Well, this has been venom-enal.

If you made it through all sixty, you’ve built up an immunity. Iocane powder style. Go hydrate or something.
