I managed an 'over the handlebars' myself a few years back. I'd just parked the car and pulled the bike out of the back. Although only a narrow road, there were Norfolk Island pines along the side (the car parks were in banks between them) and those the roots on those things play merry hell with a bitumen road by raising huge bumps.
So there I was, about roll off, on a road with really bad bitumen and an uneven surface. I looked both ways, watched a car carefully that was coming out of a nearby side street without indicating and, as soon as I knew he was going the other way, I moved off... and dropped the front wheel into a pothole the size, shape and depth of an upturned helmet. The front wheel just stopped didn't it... but I ddin't, I described a arc over the bars and landed on a shoulder. Only damage was to my pride (but I don't have any so that was fine), no scrapes on the bike, not a mark on the helmet we're forced to wear (though I'm happy to accept there could have been).

However, being an experienced cyclist, I've never gone back to that exact hole to repeat the exercise. No need to really, there are lots of other ways of amusing the wildlife when falling off.
