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: What's so special about this pen other than that it's invisible? Which is a big deal, so I get it. 
 Response 1: It's true. Did you know the appendix is only as big as your pinky and it can do all that kind of damage to you inside. 
 Response 2: I know. Are you kidding? I'm Hitler. I love this kind of shit.
