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...'. 
PROBLEM: We are in New England in 1809. John Gooding Thadeous, you have accused Jane Gooding Thadeous of witchcraft.

SOLUTION: Yeah, I've accused my wife of witchcraft. She sewed a poppet and caused me to go deaf.

PROBLEM: Thank God you said father, I thought you were talking about me at first.

SOLUTION: I actually thought he was talking about Goofy.

PROBLEM: Is that really how it works? The regular cast doesn't even know their lines?

SOLUTION:
Yep, every night we just wing it. So far, so good, but you never know when it's going to come to a crashing halt.
