Lost 3 stars for the ending
It started out funny. And oddly enough the whole spaz out, throwing chairs around the store is like a fantasy of mine. I'm kinda uncomfortable calling it a fantasy, but seriously, who doesn't look at a warehouse of cheap crap and think "I could smash this, while experiancing a maximum level of enjoyment!"
I don't want to meet the person who doesn't think like that.
Anyways. Funny movie overall, I expecially like the unexpected situations, like him sitting ontop of the guy on the nails, when we assume he'll be on the nails.
The montage was funny, but should have had a few more moments like that.
And although I can't think of a better ending off the top of my head, ass cancer was pretty weak. The cancer part doesn't offend me or anything. It's just extremely low brow. So low that it might be confused with a moustache.
You're clever guys, and I feel you can come up with a much more enjoyable ending than that. The tombstone was funny. How he got there wasn't.
