Adam Savage of Mythbusters had to go through the full body scanner, only for the TSA to miss the two 12-inch saw blades that he had in his jacket pocket. More of the mounting evidence that the full-body scanners see you naked really well, but aren't very good at spotting actual dangers.
So...they saw his junk, and missed saw blades. He mentions that his junk is offended by that. He uses profanity in this clip...just FYI.
