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: Excuse me, Paul. I think somebody spilled hot chocolate on my seat because the back of my cloud is cloudier than the front.

PROBLEM: We both sleep on the top bunk because the bottom bunk is too dangerous.

SOLUTION: It's too dangerous!  That's where people get strangulated!

PROBLEM: Anyway, I'd love to hear more about you, Pampt. You're a hair model? That's so cool.

SOLUTION:
Oh, it's just so-so. People take pictures of my hair, no big deal. Big fashions magazines.
