Last night I saw this at a Yeshiva:
Gold fish in the toilets.
Mini dollar store alarms on every door.
Stink bombs.
Bowls of gold fish on staff desks.
Caution tape all over.
Took the computer from the Menahel’s desk and replaced it with a TV monitor and put beer bottles around it.
By the way the offices were locked and the keys were taken without the Hanhalas knowledge.
During davening turned on a mic that was on the Amud.
