As a kid, going over the bar on the swings was a huge fucking deal!

I have vague recollections of some book or show where a kid went over the bar and as a result his body turned inside out. (Not sure if that was an actual thing or some fever dream I had!)

And the cartoon Recess had an episode where a kid went over the bar and disappeared, and all the kids thought he travelled to another dimension or became a god or something. (In reality he just jumped off the swing and hopped in his mom's car, but nobody saw him because of glare from the sun)
