The ending is a stroke of comic genius (SPOILER)

Oh dear lord even thinking about it sends me into fits of laughter. At the very end when Amy Smart is driving down the desert highway and she thinks she see's Val's characterat the side of the road, only to discover it's none other than Steve-O from Jackass dressed in a suit and hat with the most hilarious expression on his face, any form of interest, suspense or genuine belief in the plot was instantly lost. What the hell is this scene all about and why Steve-O? I played the scene over and over again, (ok I may have been under the influence at the time), but I swear the more you watch Steve-O's face the funnier the scene gets, what was the director thinking. Quality cameo though, I nearly pulled a stomach muscle laughing so hard
