Made a trade of my Centipede UR for a Stargate UR.
Was moving the 'pede to the truck and hit a dip in the asphalt and the game got out from under me and landed on it's front.
The result was broken wood at one side of the CP. But some putty on it to make it less obvious and hoped it would dry during the drive to the "buyers" home.
But that's NOT the worst screw up part of the story ...
I later found out the "buyer" kept that almost perfect game (except for the above)
out in the rain and it got ruined.
So, my worst screw up was trading with that guy. Grrrr.

(though I still have the SG and it's pretty nice)
RIP unlucky 'pede.
