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'm so excited. I can't believe he didn't bite your face off. 
 Response 1: He tried many, many times. That's why I'm wearing this jacket with the reinforced sleeves. I'm constantly putting my arm up in front of my face. 
 Response 2: All right, Antoinette. Roger, can you just sort of flex your thigh just a little further?
