The TSA Instagram account is a treasure trove of insane items travelers try to get through airport security.

Celebrities like Kim Kardashian and Taylor Swift may be the queens of Instagram, but there is one account that is more hilarious (and terrifying) than any other: @tsa. Yes, the Transportation Security Administration (TSA) is on social media too, boasting 508,000 followers and sharing some of the crazy things passengers have attempted to get through airport security.

While they seem to have a good sense of humor when it comes to prohibited items discovered in people’s carry-ons, it’s also slightly alarming to see what some travelers are trying to smuggle.

“Holy prohibited items, Batman,” the agency captioned one recent post. “Who knew that batarangs were so popular? Our officers have discovered quite a few this year. This time, the batarang was discovered in a carry-on bag at LaGuardia (LGA). Please pack your #batarangs in your checked baggage. #TSAGoodCatch.” That was just one of the many weapons the TSA caught: In 2015 alone they discovered 2,653 guns in carry-ons.

“Talk about deadheading,” the TSA said about another interesting find. “This crusty ol’ chap is actually a prop from the #TexasChainsawMassacre movie. He was brought through a checkpoint at the Atlanta International Airport lost and found, where as you can see, he was screened and sent on his jolly way. #TSAOnTheJob”

“This ornate jawbone tomahawk was discovered in a carry-on bag at Salt Lake City (SLC),” read another post. “Jawbone tomahawks (and all other tomahawks) must be packed in checked baggage.”

In fact, tomahawks, batarangs, and fake corpses are just some of the downright insane items TSA officers see daily; and while being thoroughly entertaining, sharing their finds with the public is also an attempt to inform travelers of what is and is not appropriate. For starters, an alligator head is fine to bring on board, but stay away from that post-apocalyptic bullet-adorned gas mask. Err on the side of caution when you’re weighing whether or not to check a more eclectic item, and check the TSA’s site for information on prohibited items. If you have specific concerns, the TSA has also launched a Twitter account called “Ask TSA” where you can share a picture of a particular item or ask a question between 8am and 10pm EST weekdays and 9am to 7pm on weekends. Just know you’ll need to check your brass knuckles and vehicle airbags, but pumpkins are okay. TSA AIrport lost and found

Here are a few more of the most outrageous discoveries:

One traveler opted to pack a homemade replica suicide vest for their journey, which, even if it’s prop for a live-action role-playing game, is still not funny.

Deer antlers, which might make a great wall ornament, also made an appearance.

While another passenger packed a…bejeweled lipstick stun gun.

And yet another ninja was stuck paying checked baggage fees.
