"While faking a resignation, gluing office supplies to the desk and covering someones cube in aluminum foil are among the most common office pranks, here are 10 of the most memorable pranks from this year's survey:
1. Placed a pair of pants and shoes inside the only toilet stall in a men's room to make it appear someone was using the stall. It sat there for hours until someone called security to check if the person had died.
2. Sent a fake love note to a co-worker from another co-worker.
3. All the women in office individually spoke to the president, confiding that she is pregnant. By noon, he 'knew' that all of his female workers were pregnant and he could not tell anyone because each asked for confidentially.
4. Called the electric company, used a co-worker's name and told them he was moving so the electricity got turned off at the co-worker's house.
5. Filled the vending soda machine with cans of beer.
6. Rigged the boss' chair to drop suddenly during a staff meeting.
7. Placed a sign on the restroom door that read, "The company ran out of toilet tissue; please use your own resources."
8. Paged a co-worker over the loud speaker claiming the CEO was looking for him. The worker went into the CEO's office and the CEO didn't know who he was or why he was there.
9. Shrink-wrapped everything in a co-worker's cubicle.
10. Put a 'house for sale' ad in the newspaper regarding a co-worker's home"
