This comes under the category of, what were you thinking?

Last year, passengers were stopped by the TSA at security checkpoints because they were trying to bring the weirdest items on their planes.

So what did the officers seize?

Chainsaws at New York’s JFK, a spear gun at Houston’s Hobby Airport, an ice axe at Chicago’s O’Hare, a knife concealed inside a baby carrier at New York’s LaGuardia.

The TSA even posted a very funny YouTube video of its most unusual finds.

Check it out, and please, the next time you fly, leave your inert mortar round at home. Yes, the TSA seized that too, at the airport in Evansville, Indiana.
