Chemistry Jokes

[Person A] Morning, do you want to hear a joke about nitric oxide?

[Person B] NO.

[Person A]

How about another joke? What do you do with a sick chemist?
(pauses.)

If you can't helium, and you can't curium, you might as well barium.
(laughs then stops.)

Okay. Okay. Today I told a joke and there was no reaction.
(pauses.)

Hmm, it's hard to make another one. All the good ones argon.

[Person B] Just shut up please.
