accidental
once upon a time, mommy and mommy's brother were playing in their living room.
mommy's brother said, "i bet you can't walk on the edge of the couch."
mommy said, "i can, too!"
so mommy walked, walked, walked, walked on the edge of the couch.
and then she fell... smack!
mommy's brother said, "uh oh."
the end.
