My friend was trying out for our school's (very little) track and field team, in the high jump. He tried to do the normal flop method, where you jump sideways/backwards, headfirst, arching your back to get over. He couldn't do it, so he tried a different technique.
He jumped, got one leg over...
and landed, straddling the bar.
He literally balanced on the bar (by his crotch) for a second or two before screaming and falling off.
