I just watched this movie the other evening. It's pretty much what you'd expect from Larry the Cable Guy. It's loaded with farting, some vomit, a slew of non-PC jokes, and is certain to offend the PC sensitive crowd.
In other words, I liked it.
If you aren't offended by the rectal passing of methane gas, sniffing a rat's ass, or the sight of a fat redneck sitting on a toilet, it's a pretty amusing movie.
