We had a few days a year when lessons were suspended and students attended self organized activities instead.

An entire class decided to sneak out instead, went to a bar and some students got drunk before coming back to school. One such student went to the bathroom, zipped up his pants without properly storing his equipment and ended up requiring medical attention including some stitches.

I never met the guy or even know who he was, but the whole school was talking about it for a week or more.
