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: Now, sit down.  Both of you.

SOLUTION: Well, there's only the one seat.

PROBLEM: Hey, that's our father you're talking about.

SOLUTION: I know, but why doesn't he have a regular job?  He wears that frilly apron around the house like a real Mr. Mom.

PROBLEM: You know, I gotta be honest with you. For a while, you were my idol. But I just gotta go work at the factory, at the plant on Factory Street.

SOLUTION:
He doesn't believe in himself. He could have been a real weatherman, right here in town, but he sold himself out. He just went to the plant because his dad did.
