Everyone seems to remember that rewarding gym class experience where we all grabbed the big top tarp thing, each around the circle, and lifted it up and down until it formed some kind of dome. At this point, we were all told to run to the middle and pull it down behind us and sit on it. It made a nice CO2 gas chamber (or dutch oven, depending on what was for lunch) for 15 seconds until it deflated, but it was kind of like going into another dimension or something. I'm not sure what kind of hippy get-together wussy PE thing this was, but it sure was colorful, maybe even magical. For a dork like me, it certainly beat dodgeball, or any other sport in existence.
