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.

 Response 1: Me? You're talking about me? You thought I was a bucket? Really? Me? The guy who's just a mailbox? Yes! I am a bucket. Yes. 
 Response 2: The tuna salad wasn't good. I trust that cafe for tuna.
