Definition: 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...'. 
Input: I'll never forget the moment that ended up in the movie trailer when Sandra Bullock says "It happened to me. It  could happen to anyone." Probably my most enduring memory of The Net, the movie I was in.
Output:
My biggest memory is when she orders pizza, man, and she uses the internet and it looks really good.
