Should the “Mentos & Cola Ass Enema” appear a bit ticklish in consistency, just remember: it?s not gay if it?s science. Plus, we were all just so happy to be together and filming and, well, you know, it’s just fun to conduct experiments on our human nature?especially when rollerskates are involved. All I know is that I about busted a damn spleen watching Jeff Tremaine come to grips with Bam Margera?s bare ass.
