So, what about the really bizarre stuff? You might be surprised to learn that batarangs (yes, like the ones used by Batman) are not allowed on planes. And, if you're a näive ninja, you might want to leave your ninja stars at home. But, hey, who tries to sneak those on a plane anyway?
But, seriously, some items are prohibited for good reason - like flammable liquids and explosives. And, let's not forget about the weird and wonderful items that have been confiscated at airports - like alligator heads and live animals. Yep, you read that right - someone actually tried to sneak a live animal on a plane!
