If you've ever had an X-ray of your teeth at the dentist, you've had a heavy lead apron draped over you to reduce radiation exposure to other body parts.
0:36 The apron, worn from the neck down, can get in the way? Who's dentist is trying to x-ray your teeth through your crotch? These people out here firing x-rays at me like they got a sawed off shotgun. You better give me that damn apron if you're that bad a shot. Give me two in fact!.
What it means is that the Lead Apron may sometimes pop out especially in the neck area and block the Xray Cone and subsequently the region of the teeth which the dentist intend to capture.
