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: Alright, I'll give it a try. I'm going to sing like a sonic blast. 
 Response 1: It's really easy to remember. Descend starts the same as down. Ascend starts the same as up. OK, maybe not. 
 Response 2: Yes, and then I'll laugh. That will attract dolphins because laughter sounds like dolphins. Then we can ride the dolphins to the shore!
