The movie: Old School (2003)
The player(s): Will Ferrell, Luke Wilson & Vince Vaughn

By day, Frank Ricard (Ferrell) is a newlywed who spends his Saturdays at Bed, Bath and Beyond. But at night—and with the encouragement of college buds Mitch Martin (Wilson) and Bernard Campbell (Vaughn), he becomes "Frank the Tank," a mean, lean, streaking machine. Oh, he's also a founding member of a brand-new fraternity... started about two decades after his college graduation.
