You'd be surprised at just how many stop motion Lego skate vids people have made, but I'd put a reasonable estimate at 5876569393022544 videos.
Lego Rodney VS Little Kid Rodney.... GO!
Before you swivel around in your chair and ask the guy next to you what that AWESOME track Rodney is gettin' hype off of (in 1984) it's...Midnight Express (The Chase Movie Theme) by Giorgio Moroder. iTunes, bro. You might as well just buy it because it's going to be in your head all day.
