There were two different versions.
The main difference is that Ryan's part is way different.
If I remember correctly it was because he just threw his original part together for what he thought was just a regular shop vid, then the thing sold like a gajillion copies and he was kinda bummed on the footy he had in such a popular video. So when it went to DVD he filmed more shit. Don't remember where I heard that, probably some old ass interview.
Also, in the second version of PJ's part there's that line where he does the kickflip frontisde 360 then tries to nollie lateflip that set. That shit wasn't in the original.
