25. Will Ferrell goes streaking, Old School (2003)
Life was good before we knew what Will Ferrell’s ass looked like. The sun shone brighter, desserts tasted sweeter, and the air was crisper. Then our world crumbled down around us when Ferrell, as Frank "The Tank" Ricard, went for a naked midnight jog after a pretty rough kegger in Old School.
We could have gone for a brief shot or two of the full moon. Instead, director Todd Phillips kept the camera right on his backside as he ran through the night air. We can still see it when we close our eyes.
