The TSA said a gun frame had been jammed in the bottom of a boot, below a sock that was stuffed in behind it in an effort to conceal the weapon. The rest of the handgun — the slide, spring and gun magazine loaded with 12 bullets — were detected among plastic building blocks inside a Black Panther LEGO set.

The bizarre sighting landed the New Jersey airport in the No. 8 slot on the agency’s Top 10 list of most unusual finds at checkpoints last year.
