10 Movie Mistakes That Should Have Stayed In

8. Will Ferrell On Sex - Step Brothers

http://www.youtube.com/watch?v=vED9n5lcq6c&t=2m38s Admittedly, this one isn't so much a blooper as it is Will Ferrell's unfettered, uncensored ad-libbing, though most of the takes, brilliant as they are, are rendered useless by the fact that both Ferrell and John C. Reilly can't stop themselves from laughing uproariously. Ferrell begins by asking, "Have you ever done it so much that you've had to put your d*** in the freezer?", and moves forward from there, declaring, "Last summer was my biggest summer for p***y". Given that the film is a comedy, does it really matter if the two of them can't say it with a straight face? Their infectious laughter would transpire through to the audience, and their reactions to the lines keeps in character with the fact that, yes, they are infantile man-children. This series of one-liners from Ferrell made me laugh more than pretty much anything else in the entire film (except perhaps for "the f***ing Catalina Wine Mixer").
