There are tons of videos out there of trick shots. Compilations like this one of people showing off their skills. A lot of them are pretty damn impressive, if I may so say myself.
You know who's not impressed? The Great One.
Wayne Gretzky starts his own version of a trick-shot video with a simple message: "Sometimes I see people trying trick shots on the Internet. Believe me it's embarrassing. So today I'm going to show you how it's done, Gretzky style."
Now if the fact that it's posted on College Humor wasn't clue enough, I think you definitely get the idea by the third shot that this is a parody. Although I think one or two of these would be doable and I'd love to see the best trick-shot champs to make them.
Personally, my favorite is the Seinfeld shot.
