HI,
Its after a couple weeks and you clip in and out without thought and your riding along day dreaming,
come up to a stop light and forget to notice the grade on the sidewalk is steep unclip on the wrong side and go down very slowly!!!!! awwwwww ahhhsshhhhoooooootttt and you laying on your back still clipped with a bike over you, and everyone wants to stop and say are you OK... yea I do that alot...
Thats the best one.. do it preferably in a resort area with plenty of pedestrians for support..
