There's Something About Mary

Best Dog Fight: Puffy vs. Ted Stroehmann (Ben Stiller) in "There's Something About Mary" (1998)

The flawlessly funny choreography of Puffy's fight sequence with Ben Stiller is all the better because you can obviously tell when there's a stunt dog (i.e., a stuffed dog) involved.... more That makes it funnier because: 1) they don't even try to make the "dog" look real; and 2) you are free to laugh because you are reassured that no animals were harmed in the shooting of this scene. Puffy the border terrier has learned some of his chops from silent slapstick comedy, which is exactly how this scene plays, only with a lot of yelling and screaming and growling added to the mix.

One of Puffy's celebrated moves comes from Charlie Chaplin's 1915 Essanay short "The Champion," wherein Charlie's boxer sinks his teeth into the seat of a rival pugilist and gets swung around the ring. Since "Mary" is a penis-centric Farrelly Brothers picture, the gag is, well, reversed: Puffy bites Stiller's crotch and gets taken for a wild spin.
