Here's what's being sold: 12 unrolled TDU cans, complete with lids and bottoms (TDU weights not included):
Bidding ends today, so you'll have to hurry. (Note that although the seller thought the cans are shot out of a boat's torpedo tubes, a commenter already set him straight about concept of the Trash Diposal Unit.)
Now you won't just have to tell your wife and kids about how you used to get your fingers all cut up rolling the cans -- you can show them!
