There was this one building, McCracken, that used to be a barn. (I went to a really old, teeny little private religious high school that used to be a boarding school out in the country, hence the need for a barn.) Anyway, it was converted into a four-floor building with a gym and classrooms but because of the pitched roof, the stairwells got narrower the higher up you went.

So we're all filing out of an English class on the second floor, and this big bear of a guy (picture Jack Black--not kidding) got the long strap of his duffel bag caught on the banister. He didn't realize what had happened until the slack on the strap gave out and bam, he went down on his ass, and everyone who was behind him piled up and we all went down like dominoes. Then the kids from the third and fourth floors were trying to come down, and they piled up, too, not to mention the kids coming in the building and trying to go up the stairs. It was a three floor, sixty kid pile up and it took forever to get everyone on their feet and on their way to the next class.

...is it sad that that's one of my funniest memories? Sheesh. Although, seeing as how the story started out in a barn, what more could you really expect?
