You get zero cool points out of pulling a prank like that.

My kid's school has forbidden stairs up to attic storage or something, but the kids think there might be a pool up there for the teachers.

That's awesome! I've used "the pool on the roof must have a leak" a few times as well. That movies has so many one-liner quotes that still live on to this day.

I very regularly refer to the act of writing code as "hacking the Gibson."
