1. Batarangs
Someone traveling from San Francisco (SFO) was feeling like a superhero one day when they tried to sneak these batarangs by the TSA in a carry-on bag. These weapons certainly win some points thanks to their good looks, but remember they need to be safely packed in checked luggage before they fly.

2. Flaming Balls
Fireworks and airplanes aren't a good match — thankfully the TSA caught someone trying to bring these exploding flaming balls onboard an aircraft at Manchester - Boston Regional Airport (MHT). Fireworks can't fly at all, even if they're packed in checked baggage.

3. Hatchet and Knives
If you can't bear to leave your various knives and hatchets at home while you travel, remember to pack them in your checked bag. These weapons were confiscated by TSA agents at John Wayne Airport (SNA) in Southern California.

4. Grenades
We can't really imagine why anyone would want to bring a grenade (even if it's inert) onto an aircraft, but it's reassuring to know that the TSA prevented these explosives from getting on board a plane. Grenades and any other types of explosives are prohibited from flying — these were confiscated at three different airports around the country during the past month.

5. Pizza
The last item isn't prohibited at all — it's just hilarious to see a pizza box queued up to get scanned alongside backpacks and laptops by the X-ray machines in Philadelphia (PHL). If you're dying to bring your favorite pizza with you on your flight, rest assured, because according to the TSA, "pie can fly!"

What's the strangest item you've seen at a TSA checkpoint?
