Yesterday a man tried to smuggle a knife onto a flight from JFK to Mexico City—and he might have gotten away with it too had he not decided to hide it inside another item he wasn't allowed to have. The TSA says the unidentified knife-wielder desperately wanted to bring his precious Leatherman blade aboard the plane. But the uptight TSA rules prohibit these sort of shenanigans! So why not sneak it aboard inside a big full jar of mayonnaise? That plan's a Swiss watch.

In a press release announcing the incident, the TSA lets its hair down a little and cheekily observes that the man "ended up eating his sandwich dry when both the knife and mayo were surrendered at the checkpoint. Okay, so he didn’t really have a sandwich with him. But he had enough mayonnaise for a month of sandwiches." Hey-o! Fact is, liquids and gelatinous stuff like mayo have to be in a 3.4-ounce or smaller container. “The mayonnaise jar was larger than that, so ironically he was trying to smuggle a prohibited item inside of another prohibited item,” Farbstein tells CBS 2.

Port Authority police confiscated the knife and the delicious oil and egg yolk emulsion, but let the man proceed on his way to Mexico City. Upon arrival, he was greeted by a hungry family with loaves of unsliced bread and a big tub of egg salad just waiting for one. crucial. ingredient.
