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: On both of my knees, I had to get the cartilage sucked out of them, but they were able to replace it with just a fine cotton batting that you usually find in stuffed animals. 
 Response 1: You're a big deal. Absolutely. I'm just saying, that some of the negative side effects are coming out. You're not a body builder. You're not some sort of athlete. You don't need this raging testosterone in your body. 
 Response 2: Well, I barely heard you walk in here, so it must be working.
