I was keeping score one night (years ago, obviously) and the damndest leave I ever saw was when this guy barely nicked the 10 pin to the right, and it somehow managed to topple only the back row. So he left the 1-2-3-4-5-6. Never seen that before or since. I don't remember if he picked it up, but I'll never forget him leaving it.
My worst leave was a 5-7-10 using a dull Thunderbolt, which at the time was considered the bomb ball to have. I thought it was a bomb, all right - damn thing was a waste of money for me and I couldn't get rid of it fast enough.

You weren't unlucky when you left that corner pin, so shut up about it already!!
