Make sure you use the facilities before you put this office bathroom trick into hilarious effect.

Step 1: Get some slacks

Get one pair of slacks and one pair of shoes for every stall in your office bathroom.

Step 2: Stuff them

Stuff each pair of slacks, from the knee down, with old newspaper. Don’t overstuff the pants, or they won’t look like ‘believable’ legs.

Step 3: Position them

Position a pair of shoes in each stall.

Step 4: Set up

Position a pair of stuffed pants atop each pair of shoes. Arrange the top of the pants to fall just right – so it looks like someone is sitting on the toilet with his pants down.

Step 5: Lock

Lock each stall door from the inside.

Step 6: Start a rumor

Start a rumor that there’s a stomach bug going around the office that is keeping people on the john.

Step 7: Enjoy

Enjoy the chaos that ensues as increasingly desperate people try to figure out who is hogging the bathroom.
