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: Oh, you're talking my wife up there? You want to sign my wife?

SOLUTION: I want to sign her, but she hasn't done anything that I haven't heard before. If she's got one piece of original material, I'd take her.

PROBLEM: You guys, I can't keep up this charade anymore. I'm so tired of pretending to have an adventure. I want a real adventure.

SOLUTION: Charles, why didn't you say this before? I'd love to have a real adventure.

PROBLEM: I feel like we were gone forever.

SOLUTION:
Yeah, and you know what's weird? I had the weirdest dream.
