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: So your husband on board with a murder mystery game night? I know he usually likes things more lavish. 
 Response 1: Yeah, Don has said he thinks it's going to be professional actors and there's going to be a formal dinner. But it really all comes in a box. 
 Response 2: I agree but look there, the title is "you know you know that you know knows, you knows?".
