It's a genuine concern.

I remember a couple of years ago the local used car dealer that is on the TV incessantly walked through a checkpoint in Denver. Several screeners, including the x-ray operator stopped to gawk at this guy. Even when the belt was rolling, the x-ray op was looking at him while he put the rings back on all 10 of his fingers.

Same thing happened to Trevor Pryce just after he was traded from the Broncos, and Johan Petro a couple of days after the Nuggets were bounced from the playoffs in 2009.
