In this part of the film, Adam Sandler's character has to make a presentation about his ideas for a new hotel. Just before the presentation, a bee stung his tongue when he was eating an ice cream, so he can't speak properly. His friend can understand him, and translates for him.
It's a good listening exercise, but above all, you can really hear the "song" of English - the intonation going up and down and the stressed words stronger than the others. If you want to improve your English pronunciation, trying to imitate this rhythm and intonation will really help you speak more naturally in English.
