Custodians take the brunt of senior pranks. There was one in my school district in which 5 geese were let loose inside a high school, plus a few gallons of maple syrup on the floors.

This was several years ago, but the custodians can still show you places where they could not get the dried syrup out, plus do you have any idea how much a full grown goose shits?

(This year for a senior prank, in the same high school, kids got through 2 locked doors onto the roof and did over $10K damage to a large skylight, attempting to take it off.)

My grandfather was head of maintenance for a college for a few decades. I have a picture of him dipping foam soap bubbles out of the central fountain on campus. I remember thinking it was funny as a kid, but, honestly, now that I'm an adult I think it's really a shame that someone as kind, hardworking, and skilled as my grandfather had to pick up after a bunch of thoughtless brats.

Not only do I think the goat thing is a funny prank, but I understand both the plight of the working man and the urge to rain on parades.
