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: I happen to have some mannequins in the back of my pickup truck. We could put them into your beds, and then once your parents are asleep or meditating or whatever they're doing, you can come to Van Nuys and I can show you what the real world's really like, with feelings and emotions.

SOLUTION: Oh yeah, and Trish and Laura can cover for us.

PROBLEM: I'm never going to say the word horse as long as I live.

SOLUTION: Well, why would you promise that? We're at a stable. You can say horse.

PROBLEM: I do have to move on to the next town, I can't stay here forever in Chicago. Not a big jazz town. 

SOLUTION:
All right, well, I understand, but you're welcome back anytime.
