Given the prompt and a response, classify the them to "yes" if response is "yes, and" type. Otherwise classify it as "no". "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..."). 1 In short, a "Yes, and" is a dialogue exchange in which a speaker responds by adding new information on top of the information/setting that was constructed by another speaker. Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange, although it could be the case if it agrees with the description above. There are many ways in which a response could implicitly/explicitly agree to the prompt without specifically saying 'yes, and...'.

 Response: Look, I can't help that I have a speech impediment.  I try the best I can.  I got to do what I'm relegated to.  This guy, he gets a big number, and he sounds like a squeaky door on Halloween.
no

Prompt: Officer, would you mind checking on our associates in the video store? There's a large man.

We're just worried they're taking a little too long in the Blockbuster Video store. 
 Response: I find that hard to believe about every movie every made.

no
