Our gym teacher would have us all do this on our own. Then while we were under it, he'd start walking away saying, "Alright now you guys I'm going to grab a cup of coffee, no one go anywhere until I'm back!"

Then he'd wait by the lights until we all started wondering where he went. Then he'd kill the lights. Then he started making growling noises and talking in a gruff voice, like, "Ah what have we here...!"

Then he'd take one of those extendable poles to open windows high on a wall and reach it through the center hole of the parachute and start prodding around "hunting for kids".

This was in 3rd grade and it never got old to us. Once I remember someone decided to try to grab the pole and he went along with it as if he was fishing.

Great, great gym teacher. They literally aren't allowed to be like this anymore. We played all sorts of "dangerous" games that involved hurling balls at one another, careening around the gym on plastic butt scooters, etc. It makes me sad for future generations :(

[edit] Fun fact, he's actually the brother of Bill Parcells.
