Rock stars are experienced travelers and know the TSA regulations at airports off the top of their head. Unless you're Flaming Lips frontman Wayne Coyne. Then common sense is difficult enough to remember.

At one of the busiest traveling times of the year, where airport security freak out if you forget to take your belt off, Wayne packed a grenade in his carry-on luggage. A motherf***ing grenade! Naturally, police shut down the terminal where he was at Oklahoma City Airport until they could get a hold on the situation. They eventually determined that the weapon he packed wasn't live, according to E! Online.

Despite being a moron, Wayne was at least an apologetic moron by taking to Twitter and posting a photo of himself flashing a peace sign. "Sorry Sorry Sorry!! Everyone that was inconvenienced because of my grenade at OKC airport!!" he tweeted.

Here's hoping your holiday travels aren't nearly as chaotic!

What do you think of Wayne bringing a grenade into an airport?
