4. Butt X-Ray
Ryan Dunn (R.I.P.) will always be remembered for this climatic sequence from 2002's Jackass: The Movie in which he shocks and appalls an unsuspecting doctor and his staff when they take an X-ray of his abdomen to discover that there's a matchbox car stuck in his rectum. More impressive, though, is how much Dunn manages to disgust his fellow Jackasses while lubing himself up and inserting the toy into his rear end beforehand in a hotel room. That takes some doing.
