I really hate to go into reruns, but it's
[j]ust an inert tube used to carry a missile around. Kind of like the container in which you get posters mailed to you, only olive green with some numbers stenciled on it and it once upon a time held something even cooler than a Kill Bill poster. The only way it could possibly be dangerous is if you beat somebody with it, but it would take a fair amount of beating to get anything done since it has the density and drag coefficient of one of those big kiddie whiffle bats, only more awkward to hold. Actually, if you wanted to kill someone with it probably the easiest way to do so would be to take some heavy-duty scissors, snip off a piece, and stuff it down their throat in hopes that they choke.I don't know what it is about green plastic tubes that sends reporters and Barney Fife into a total Code Brown, but they sure do.
