We rented the movie because we are dressing like Cheech and Chong for Halloween and wanted to get some of their moves and mannerisms down. I watched the movie several years ago and probably thought it was funny back then. Because of the type of movie it is I should have been prepared for the language but I wasn't so really didn't enjoy the movie at all.
This was a pretty funny movie, I would recommended it. The only issue I had with the movie is that even though it has some funny scenes, the movie as a whole is kind of all over the place and doesn't really have a story line.
