when you fill a box full of frogs, and set it loose in a confined space for maximum lulz. 500 is a good round number to work with. make sure to always have an escape plan, because accidentally frogboxing oneself can be a harrowing experience (as was duly noted on the season finale of michael and michael have issues).
while he was taking a shit, we frogboxed michael and barricaded the door from the outside as we listened to his screams of pain and agony through the wall. it was hilarious. i think i pissed my pants i was laughing so hard. seriously, what kind of pussy is afraid of frogs?
