This conversation must have gone something like this: "Sorry, sir, but spearguns are not allowed on the plane..." OBVIOUSLY.

This is a World War II blasting machine taken off someone in Atlanta, GA.

Who honestly tries to bring a cannon in their carry-on?

That's a cane that also doubles as a stun gun.

Just imagine someone actually trying to use bear spray in the enclosed environment of an airplane? No thanks.

Someone in Vermont honestly thought they could board a plane with this giant wooden mallet.

Of course, people also try to sneak in plenty of hidden knives...like this one concealed in a lipstick case.

Phone case or knife?

Yes, that is a mini saw hiding inside a Bible.

Even though everything on TV and in movies says you can't smuggle drugs onto a plane, that doesn't stop everyone. These guys tried to smuggle cocaine aboard by hiding it in some raw meat.

Hollowing out school books isn't a very effective drug smuggling method.

Then, of course, you have the people trying to bring their sword canes on the plane.

Obviously you're going to get caught with this.

Seriously?

Even though it should be common knowledge that you can't bring your gun with you on a plane, people still try. This is America, after all.

Think the attempted gun smugglers are bad? They're nothing compared to the attempted grenade smugglers.
