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: He pulled the old double talk on me. He doubled everything I said, but he just changed the pronouns.

SOLUTION: He changed the "you"s to "me" and "I".

PROBLEM: You're saying sleep fighting is one of the few sports without a paddle. It's not a sport, so that's a big problem. It's a weird thing you do in your sleep when you're hitting people.

SOLUTION: When I'm dreaming, it's a sport though. You should see the professional boxers that I can knock out.

PROBLEM: Tony, I gotta be honest with you. I don't think this mall is ready to open its doors today. The popcorn machine isn't popping yet, the clothing stores don't have all the clothing finished yet, the soda machines don't have the bubbles in the soda yet.

SOLUTION:
Well, sir, I mean, I can get all that started now.
