Candy is trying to get her boyfriend Benny to quit smoking.
(C=Candy; B=Benny)
C: Benny, your breath smells like an ashtray. You've got to stop smoking!
B: I know. I want to, but it isn't easy.
C: Why don't you chew gum instead?
B: I can't. I've got false teeth. Remember?
C: Oh yeah. In that case, how about eating candies?
B: If they're as sweet as you, no problem.
C: Cut it out, will you? I'm serious.
B: Just kidding. Do I get a kiss if I really quit?
C: I don't like the taste of ashtrays. Maybe tomorrow if you quit right now.
B: OK, you're got a deal.
