One of my favorite scenes is when Borat is trying to learn how to tell Americanized jokes. It's funny to think about how the joke coach really thinks that Borat is that stupid. He is putting on an act, so that the audience laughs.
Borat is classified as a Mocumentarie- a fictional movie presented as if it was a documentary. There was tons of controversy when this film was released. Cohen was looked at as sexist, homophobic and racist. Cohen has been sued multiple times, because he lied to the people that are shown on the film. He was acting, and many didn't appreciate this.
I just think that these Americans shown in the film were embarrassed when it was released, and now they want to defend certain things they said.
If you haven't seen the movie, watch it! Keep in mind that Borat is acting, and the other characters aren't. Check Borat out on Myspace!
