Flaming Lips singer Wayne Coyne shut down an entire airport after trying to bring a grenade on a plane.

No ... really. You can't bring a spork on an airplane, but he packed a grenade.

According to TMZ, the 51-year-old singer shut down Will Rogers airport in Oklahoma on Nov. 10 after his luggage triggered an alarm. According to the police report, he told the TSA the grenade was dead, but guards nevertheless followed protocol and shut down the airport while they figured out the situation.

I repeat: Wayne Coyne thought he could bring a grenade on an airplane.

According to Fuse, the singer and his wife were headed to Los Angeles to see previews of his band's new musical "Yoshimi Battles the Pink Robots," and told the police he was given the grenade as a joke at a party.

The TSA isn't really known for its sense of humor.

As if it needs to be said, grenades, along with fireworks, dynamite and other explosives are specifically prohibited from being packed in carry-on or checked luggage. As are machine guns, flamethrowers, anti-aircraft guns, cannons, bazookas, mustard gas, hydrogen bombs, suitcase nukes, and those bombs that look like bowling balls with fuses you always see in cartoons.

The singer later tweeted an apology to anyone "inconvenienced" by the debacle.
