pee-your-pants hilarious I rented this with my friend one night, some years ago, I still consider it the best comedy I've seen in my entire life. We were literally in pain all through out the film, we laughed so hard that for most of the movie we were on the floor holding our stomachs! Then we watched it again right after and then the next day and laughed as hard as the first time. I remember Mark-Paul Gosselaar from Saved By The Bell, I had no idea he could be this funny. The cast is diverse and completely wild, especially the possibly-suicidal-roommate candidates that the two main characters are trying to lure to stay with them. Corey Page (from Heartbreak High) is completely phenomenal as the over-the-top angsty, brooding goth-rocker Matt and Lochlyn Munro (Charmed) is just too much as the crazy frat guy Cliff, these two guys gave us the best laughs. Also I liked the relationship between the main characters, played by Mark-Paul Gosselaar and Tom Everett Scott. It's that kind of "lets go do something stupid together" kind of thing and you can also see they really care about each other. As a hilarious comedy, the movie also has a little depth to it towards the end, which i really liked.
Also for Buffy fans there is Alyson Hannigan who is a great comedic actor as you can see from the American Pie-movies and of course from Buffy.
If you like the Pauly Shore-type of humor, and crazy ideas and general crazyness, you should love this film. There wasn't a moment during, that I wasn't completely thrilled to be watching it. I give it 10+!
