Not really a Jackass so much as a dumbass!
Johnny Knoxville tried to bring a grenade on an airplane!
Okay, okay, so the grenade contained neither a fuse nor powder, making it essentially harmless, but still! You can't even say the word "Bomb" without airport authorities freaking out!
Knoxville had the fake grenade in his carry-on luggage and it was immediately noticed by airport screeners this Thursday morning at LAX.
Nice to see they are paying attention!
Knoxville was subsequently detained and the LAPD is investigating further.
Next time leave the explosives (or lookalikes) at home!
