Oh and you can bet the rest of the 'frat pack' (Stiller, Wilson, Vaugahn et al) will all make desperately unfunny cameos throughout the film to distract the audiences attention from the fact that there is little or no plot and the film is basically just an excuse for a bunch of actors to piss about on a film set for several months showing off their, so-called, hilarious improvisational skills.
