TASK DEFINITION: Given the sentence, generate "yes, and" response. "Yes, and" is a rule-of-thumb in improvisational comedy that suggests that a participant in a dialogue should accept what another participant has stated ("Yes") and then expand on that line of thought or context ("and..."). 1 In short, a "Yes, and" is a dialogue exchange in which a speaker responds by adding new information on top of the information/setting that was constructed by another speaker. Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange, although it could be the case if it agrees with the description above. There are many ways in which a response could implicitly/explicitly agree to the prompt without specifically saying 'yes, and...'.

SOLUTION: Hank, if you say filigree one more time, I'm going to smack you.

PROBLEM: Can I say something?  You know, I raised these concerns months ago when Mr. Mitierry himself kept talking about putting fluids that belong in automobiles into foodstuffs and everyone said I was crazy.

SOLUTION:
Well, fortunately, some saner heads prevailed.  It's coincidental, madam, that your theory worked out, but, you know, let's let the board run the company, all right?  It's not up to one, uh, hard-headed democracy-breaker.
