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: Craig, you were supposed to infiltrate that dinner party the other day. You dressed up like the most ridiculous version of a waiter. You went in and said "I'm definitely not a spy".

SOLUTION: OK, I may have done that. But, I felt everyone should know exactly who I was so that no one was caught off guard.

PROBLEM: What were you screaming about over there behind the couch??

SOLUTION: We just uh... we just talking about, uh, temperatures. You know how in Europe they got different temperatures than here.

PROBLEM: OK, I'm going to go in there.

SOLUTION:
All right, Sherry. Please, be careful. Make sure you hold your arm out.
