Some might feel that the outtakes during the end credits are the funniest part of the movie. Now that would be a mean thing to write and I personally would not think of doing that. Having said that, you should be prepared of something really silly to say the least.
The movie works on a bare minimum and some might like the humor more than others. It will depend on taste of course ... overall this is quite decent I reckon, with some jokes/scenes that work and others that I think fail ... watch the trailer to get a feeling and decide if that is something for you or not
