Following on from the story that Johnny Knoxville allegedly attempted to take an unarmed hand grenade aboard a flight at LAX, the Jackass has given a full explanation on his website.

It seems the prop-grenade was packed into Knoxville's hand luggage by a wardrobe girl following an MTV shoot. The Jackass says:

I should have checked my goddamn luggage through and through, but I didn't and now we have this incident. From what I hear, all the tabloids are saying it was a real grenade, but that's bullshit. They just said that to make a story out of it, because if it was real I never would have been allowed to board my flight to Miami an hour later. Anyway, it was a mistake, and I just landed at the Miami airport. Damn

Damn indeed.
