A harpoon gun, hand grenades, Bat-a-rangs (twice!), a "morning star" spiked flail, a 60mm mortar round, and of course handguns: These are all things you can't carry onto an airplane. Ditto with these weird circular multi-bladed things, labeled "Fantasy throwing stars:"
But that doesn't stop the millions of folks going through airport checkpoints each year from trying to smuggle these things through—often in carry-on luggage. With firearms alone, there were 1,477 discovered instances in 2013 alone, which is about four per day.
With such rich, never-ending fodder, it's no surprise that the Transportation Security Administration has attracted some 88,000 followers to their Instagram page, which might as well be called "Photos of crazy sh*t we pulled out of people's bags." Aside from handguns and overengineered shuriken, there are the more unusual subgenres of weaponry, like Knives Hidden in Ordinary Objects (lipstick, cell phone case, comb, cane):
Then there's the Stun Guns Designed to Look Like Ordinary Objects (lipstick, cigarette pack, cell phone):
Should be hashtagged #nofilter
To the designer: Maybe the button that says "STUN" on it kind of gives it away
And with some of the more amusing would-be smuggled items, you can almost hear the offending passenger's protests, like with this one:
"But sir, it's not a gun--see? It's a knife!"
This guy's done the previous guy one better: Not only does this "gun" feature a knife, even the bullets contain little hidden knives.

As Wired writes in an article interviewing the TSA folks behind the page, "Despite its popularity, TSA's Instagram account is ultimately something it really wishes didn't exist." The purpose of putting it up is part PR, letting you know the TSA is finding this stuff, and part educational—assuming the folks who like to fly with this stuff can be educated.
