Mediocre again.
I know it is a comedy and therefore doesn't have to make sense. However, I think it would be funnier if there was an adversarial relationship with the other teachers...similar to the scene with Ferrel's character. No adult would put up with his behavior much less be kissing his tail. Especially the hot chick. Chicks at that point in life would not even acknowledge an immature arrogant jackass. Anyway, I am sure I am over analyzing it. But it would be funnier if the adults blew him off like the kids have done a few times...ie: steroids question and weight lifting scene. Especially the Principle. It would be funny if there was some rivalry there. The Principle should be making him look like a buffoon during their encounters. It will help with the audience when this idiot finally does hook up with the hot chick. Because you know that is coming.
Also, I tweak the pitching scene at the dealership. I have Ferrell's character catching. Dude throwing a heater that Ferrell catches with his nose and dude strutting off to his Bronco. While Ferrell cusses him and points out that he is a loser for driving a 30 year old Bronco and not a BMW. Should have been some laughing and pointing at his dancing on X too.
