Oh man, i love it when that happens. Once, I was flying down 15th in Center City Philly (about a year ago I guess), drunk as a skunk at ~11:30 at night, with little skinny flatbars, and "busted out" a huge balls-to-stem skid, no obstacles in the road, but those little tiny bars... Front wheel adruptly twisted sideways and I flipped over, flew through the air etc., of course it happened in front of a bar where lots of people were standing outside... awesome.
