To get in good with the Americans, Matthew Pritchard, host of the MTV UK prank show Dirty Sanchez, took it upon himself to drink heavily and piss on Dolph Lundgren , who symbolized everything anti-USA in Rocky IV, during a 14-hour flight from Amsterdam to Nevada. Pritchard downed a Xanax for the long trip to Las Vegas, but didn’t realize you weren’t supposed to take the drug with alcohol.
