Teacher:Given the sentence, generate "yes, and" response. "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: I just came up to tell you that if you plan to move back into the great seats in front of me, I'd like you to be quiet and respectful of Yngwie Malmsteen, who happens to be a person by the way.
Student:
Right, but he's up there with a whole band. So, we thought the whole band was also his name, like Dave  Matthews Band.
