Back in college they would do the senior prank thing. It ended when I was a sophomore. The seniors broke into the science lab building, plugged all of the sinks and drains on the ground floor and turned all of the water on. I don’t recall if it was for all night or the weekend, but millions of dollars of damage to the building and equipment.
And this was 40 years ago at a top-notch engineering school.
They put a stop to any type of those “prank” days after that.
The engineering school I went to? We would rappel down the side of the coed dorm, that is until campus security came by and made us stop.
