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.

 Response 1: Just like in our vows. Now, let's take a run at that mountain. 
 Response 2: I mean, what is a doughnut if not a sugar bomb that explodes in your body? That's what my granddaddy used to say. And then he started making real bombs.
