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: The doctor said my heart was too big. It was a joke heart. I guess it was a "you had to be there" situation. You're sweet to laugh. 
 Response 1: Happy anniversary. I never would have guessed. You look so young. 
 Response 2: Oh, sweety, you'll get laughter from me even if it's fake.
