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 hate to be the bearer of bad tidings, but there's a cockroach out there. 
 Response 1: Gary's out there? 
 Response 2: Oh, Mr. Two Horses. Nice to meet you. My name is Chaz. Not short for Charles. Isn't that funny? My dad was Charles and his father was Charleston. So it's getting shorter each time.
