Step Brothers

When Brennan's (Ferrell) mom Nancy (Steenburgen) and Dale's (Reilly) dad Robert (Jenkins) get married, the 40ish living-at-home losers find themselves sharing a bedroom, making for some serious sibling rivalry until the men/boys bond over their shared John Stamos crushes and their contempt for Brennan's brother Derek (Scott), an egotistical corporate suit. Ferrell and Reilly masterfully channel their inner brats while maxing out their knack for getting laughs from gross-out gags (like it or not) all the way up to the happy sappy ending.
