"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 2

Prompt: Testing wall strength. 
 Response 1: You know what? I'm just going to run right at this. 
 Response 2: Believe me, I know. I think that sounds great. But that is not what we got invited to.
Response 1

Prompt: OK. Good. I wasn't going to correct you. I'm not particularly bright. But, boy do I have oxygenated lungs.

 Response 2: Dark Crystal, I can't believe you woke up.
