Batman and the Joker are sitting beside each other on a bed, Joker with a crossword puzzle, Batman with an ice-cream sandwich.
Joker: I have something to tell you. Promise you won't hit me.
Batman: You want some ice-cream? Here, take a bite.
Joker: No thanks. So, uh, I had a guy on the inside at Wayne Enterprises...
Batman: Mmmm...
Joker: ...in the financial sector...
anyway, he says he might be able to secure us enough cash to bribe the guards to look the other way when we make our escape attempt.
Batman: Mmhmm...
Joker: Remember the escape plan we talked about earlier?
Batman: ...
Joker: Are you listening?
Batman: I'll be honest, I haven't heard a word you've said. I'm having a love affair with this ice-cream sandwich.
Joker: Come on, Batsy, this is serious. Are you in or out?
Batman: I'm out. I love it here!
Joker: ...
Batman: You know, I haven't had a vacation in years? I'm relaxing, I'm sleeping well.
Joker: You're doing time.
Batman: I'm doing the time...
of my life!!
Joker:
Zsasz is walking by their cell.
Zsasz: Hey! What up, Batman?
Batman: Hey! Zsasz! (turns to Joker) Z's checking out today.
Joker: Oh yeah?
Zsasz: Yeah.
Joker: Well, I guess every vacation has to come to an end some time.
Zsasz scowls at Joker and slowly walks away.
Batman: You just made a fool of yourself in front of Zsasz.
Joker: ...
Batman: ...
Joker: I have the worst ****ing roommate.
