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 know, this is what I came here for. We gotta find some samples or I'm not going to feel like I have worth as a human being.

SOLUTION: Me either, Martin. I'm hungry and I don't want to buy food. So I came to this corn maze because that seemed like the quickest way to get free food.

PROBLEM: There's a possum and part of a raccoon.

SOLUTION: Let's take part of that raccoon, put some cheese on it, and double fry it!

PROBLEM: Oh look, your buttons have only become larger since I last saw you.

SOLUTION:
It is because I have, how you say, shrunk. I am smaller.
