Grandma's Boy. This movie is my go to film for repeat laughs. As a gamer, I have a deeper appreciation for this film than your average film go-er, even though there are blatant inaccuracies in the film.
That being said, the stoner comedy is great fun, focusing on a bum who has to move in with his Grandma after being evicted because his roommate spent all of the rent on hookers. He works for a fictional video game developer as a tester. A new piece of eye candy is brought in to help finish the developers current project, and love is thrust into the air.
It is cheesy stoner fun, but I deeply enjoy it, especially because of the execution of the humor.
