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: I'll take his heart if he don't want it. Complementary, of course, because obviously he don't want his heart. 
 Response 1: I'm trying to wrap my brain around this. That would make one Build-a-Bear with no hearts, and your bear would have two hearts. 
 Response 2: In Primus? It's every clown's dream to join Primus.
