Definition: "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..."). Given a prompt and two responses, identify which response is the type of "yes, and". Indicate your answer by 'Response 1' if the first response is correct, otherwise 'Response 2'.  Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange.

 Response 1: It will mix with the cotton candy you're wearing. And then it will all melt. And then I know my shift has ended and it's time to go home. 
 Response 2: Oh, my God. Umbrella is actually half of my last name.
