Dumb and Dumberer: When Harry Met Lloyd (2003)

It's the first day of school when Dumb literally runs headfirst into Dumberer. It's a collision of the clueless, a meeting of the mindless and a bond of the brainless. Still just hormone-fuelled teenagers, Harry and Lloyd know they will be friends for life...but they just have to get through this disaster called school and this tragedy called puberty. No girl, no jock...
