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 am willing to meet you halfway with this, Mr Attorney General. My assistant stays in the courtroom, and I'll stay focused on the trial.

SOLUTION: But now, look, I don't want you do any of that stand up. Even if the gallery asked for it, you gotta stay right on track. Just do judge stuff, son.

PROBLEM: Mrs. White, what else to you draw veins on?

SOLUTION: I add veins to birds, trees, tortoises, my own hands and feet and legs.

PROBLEM: Daryl, you are the only person that's come by to place a bid.

SOLUTION:
That's true. One fellow came by one time and we thought he was going to place a bid, but that's not what he ended up doing.
