It always fun to do something forbidden, or something that is considered to be inappropriate. And John Beckwith and Jeremy Grey are the masters of doing some of those inappropriate things. They are the wedding crashers and they know how to do it with a great style. Coming from Steve Faber and Bob Fisher, who were the writers, and the director David Dobkin, Wedding Crashers is one of the ultimate comedy pieces ever to be made in the movie making history. In reality those two are divorce mediators and they sure enjoy in taking advantage of the situation. That is why they are crashing weddings at the first place. Since the two of them already have lots of experience in crashing the weddings, it's no wonder that their next target is really important person. After they find out in newspaper that Treasury Secretary William Cleary is getting his daughter married, and that it would be a social event of the year, this gives the opportunity to take the game to the new level. Both of them meet two gorgeous bridesmaids Claire and Gloria Cleary, on the wedding, after they manage to get themselves in, and at the same time thinks of ways to seduce the girls. But, while John is falling for Gloria, Jeremy is freaking out because of the psychotic Claire.
