One group of Montreal partygoers took the concept of “bouncing off the walls” a little too literally, sending their downstairs neighbor’s ceiling tumbling to the floor during one rager of a house party.

“Oh my god!” the tenet exclaimed while surveying the chunks of drywall strewn across his living room floor, the ceiling still bouncing to the bassline of Calvin Harris’ “Outside.”

Thankfully it appears that none of the tenet’s party animal upstairs neighbors ended up plummeting through the floor and into his apartment below, the event came to a screeching halt later that evening once the building’s power was shut off, per 6ixBuzzTV.

Building capacity: It’s more than just a number.
