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: We are in New England in 1809. John Gooding Thadeous, you have accused Jane Gooding Thadeous of witchcraft.

SOLUTION: Yeah, I've accused my wife of witchcraft. She sewed a poppet and caused me to go deaf.

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'm not pointing fingers, that's for sure. I'm not. I'm only looking at one person though.

SOLUTION:
Right, and that's just to confirm we both don't know who fell asleep on stage.
