Teacher: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...'. 
Teacher: Now, understand the problem? Solve this instance: Prompt: I know you cast members can't point with one finger, I get it. 
 Response: That's right, exactly, I have to point with two, because in some cultures it's rude to point with one finger. And also, there's an urban legend that Walt Disney always pointed with two fingers because he always had a cigarette in his fingers.
