Johnny 'Splains The Grenade

On his blog, Jackass star Johnny Knoxville explains how he happened to be carrying a dummy hand grenade in his luggage.

"A few days ago, I was filming some commercials for this show we are doing for MTV called Nitro Circus, so I took a bunch of silly props in my carry-on bag to the shoot. Well, when the shoot was over, the wardrobe girl packed my luggage so I could go home and, unbeknownst to me, she packed a FAKE hand grenade (a prop grenade that I'd taken to the shoot) in the front zipper of my luggage. Needless to say, when I was packing to go out of town this morning with my girlfriend and daughter, I didn't see the FAKE grenade in my luggage."
