Did you know the Transportation Security Administration has a blog? It’s true. The TSA Blog also has a fun recurring “Week in Review” feature, which highlights some of the crazy things TSA agents discover at airport security checkpoints.

For example, last week the TSA reported that they discovered 30 firearms. Oh, and there’s more: 25 of those 30 guns were loaded and 13 of those loaded guns had rounds already chambered.

And it’s not just guns! The TSA Blog notes that agents “continue to find inert hand grenades and other weaponry on weekly basis,” because apparently people are just constantly heading to the airport with inert hand grenades. (The blog has published two posts on why inert grenades are banned.)

“I know they are cool novelty items, but it is best not to take them on a plane,” wrote Bob Burns, better known as “Blogger Bob.” (Bloomberg Businessweek wrote about Bob last year, and he called his style of blogging “the corny dad approach.”)

The blog also reported some peculiar items that were found, including a sword cane (at Memphis International Airport, if you were wondering). A trip back through these “Week in Review” posts shows that odd items aren’t actually that rare. People brought an inert World War II-era bazooka round, a pen pistol (!) and, somehow, additional sword canes.

Earlier this month, the blog also rounded up some interesting tidbits in a discussion of what TSA agents found in 2012. The TSA screened more than 637 million passengers last year, finding 1,543 firearms in carry-on bags at checkpoints (more than 1,200 of those guns were loaded), a grenade launcher, a spear gun and “an explosively-viable cannonball.”

Look, sometimes it’s tough to remember if you packed everything you might need before heading to the airport. But at a certain point, maybe you want to leave the cannonball and sword cane at home.
