My best is bass boat anchor that fell outta some dumb mass's truck with no tailgate. The wife said she was behind this outfit going 55mph down the highway and he hits a pothole and the daym thing comes rolling out down the highway.

She hits it and somehow get all flopped up inside the rear fender well and lodges itself in there so tight, the tire tread gets sliced up before she can safely get pulled over.

I looked for that truck for several days(small town). I was gonna return his anchor to him via rectal implantation.
