1/ A bartender cleaning a glass. He responds to a question from off-panel with not even a hint of interest.
Metamorpho (OP): What do you do with a dead chemist?
2/ Still cleaning.
Metamorpho (OP): You hear the one about the guy reading a book on helium?
Bartender: He couldn't put it down.
3/ Still cleaning.
Metamorpho (OP): Hmph. Well, you know what they say. If you're not part of the solution--
Bartender: You're part of the precipitate.
4/ Still cleaning.
Metamorpho (OP): That one too, huh? But do you know why you can't trust atoms?
Bartender: They make up everything.
5/ Will that glass ever get clean?
Metamorpho (OP): Grr. This is harder than I thought. All the good jokes--
Bartender: Argon. Heard it.
6/ Nope. It's still being cleaned.
Metamorpho (OP): Fine!
Metamorpho (OP): What do you call a benzene ring with iron atoms instead of carbon?
Bartender: A ferrous wheel. Next.
7/ Metamorpho sitting at the bar. He's got a number of bottles and glasses strewn in front of him, but is indiscernible from his usual jovial self. The bartender, from behind, still hasn't finished cleaning that damn glass. It may never be clean.
Metamorpho: This would be a lot more fun if I could get drunk.
Bartender: I assure you, it would not.
