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'm enjoying this theater class so much that I want to hear from the teacher. It felt like he had an idea and hasn't spoken.

SOLUTION:
Oh, all I was going to say, you know, as we're waiting for Frank to get back. Um, Roger, I think maybe we'll try something different. What if we were to cover you with some sort of salve, would that allay your phobia of silk robes?
