"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.

Prompt: All right. I guess one of us should go back out there. 
 Response 1: Okay. You can go. 
 Response 2: Yeah, I do. I also like to look in people's disgusting mouths.

Prompt: Are you the American Baker? I've heard of you. 
 Response 1: Why, yes I am. Steve. People call me Steve. A little difficult to say "American Baker" all the time. 
 Response 2: Yeah, and how would you explain a raccoon just getting up and riding a bike? Maybe Samantha and I should run away together and try to find the diamond mine.
