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.
Input: Prompt: Gregor, Svetlana, Igor - come. We're going to say sing Happy Birthday. 
 Response 1: Ketchups don't marry each other at all. Marry ketchups means mixing them together. Look what I'm doing here. 
 Response 2: Remember, we cannot sing Happy Birthday from Mildred and Benny Hill, we have to sing pre-approved, royalty-free TGIFriday version that we all know very well.

Response 2
