There's a video montage of 20 people being punched in the face. In movies, of course.
Actually, it's 18 people, one camel and one horse. (--The camel punch is from "Conan the Barbarian". The horse punch is from "Blazing Saddles".)
And if you want to get REALLY technical, it's a horse, a camel and 17 people being punched in the face . . . and one woman being SLAPPED in the face. (--There are no closed fists in the "Airplane" clip.)
