What is the name of the movie where Dennis Quaid plays the role of a drama teacher in school?

The scene from the movie I am looking for is where Dennis Quaid enters into a bar scene with some of his students, I believe they are college students? and puts on an act like he is severely depressed because he had just over gone a heart breaking divorce and he wins the attention of an attractive lady at the bar than ends up leaving the bar with her, while his students watch his performance unfold and learn how he does it?
