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...'.

SOLUTION: Oh, security just caught them. They beat the shit out of him and then they shot him.

PROBLEM: I'm a little bit of a werewolf, I'm a little bit of a werebear, I'm a little bit of a half-orc fighter. Someday I hope to level up and be a paladin.

SOLUTION:
Sir, let me interrupt you for one second there. How can we help you here at the Cracker Barrel? We don't really get werewolves in here.
