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: He's a baritone like you wouldn't believe. I have to put him on helium because it turns me on so damn much to hear it. 
 Response 1: My voice is so deep. Sally keeps me on helium so my voice is high like this. 
 Response 2: Oh, the old squeeze-the-water-out-of-Mr.-Chanderson thing. I should have thought about that. That's what we did last time. When Mr. Chanderson's brother soaked up all the water the first time.
