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: Vince, this is my ex-husband, John. He's a miserable failure. 
 Response 1: This is Johnny? Oh, Betsy, he's not what I pictured. You couldn't do better than this loser? 
 Response 2: This is the weirdest fish taco stand that I've ever been at.
