Does April Fools' Day (or the mere thought of it) strike fear in your heart? Do memories of walking into your aluminum foil-covered office still haunt you at the end of every March?
Or, do you spend 364 days of the year plotting the mother of all pranks against your co-workers?
Whichever side you fall on, 32 percent of workers say they have either initiated or been on the receiving end of an April Fools' Day prank at work, according to CareerBuilder.com's annual April Fools' Day survey.
"Pranking at work can be risky business," says Rosemary Haefner, vice president of human resources at CareerBuilder.com.
"When determining whether a prank is a good idea on April Fools' Day, employees should consider the worst case scenario of their joke. Will his or her joke simply result in a laugh from fellow co-workers? Or could anybody, including you, lose their job?"
While faking a resignation, gluing office supplies to the desk and covering someone's 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 CEOs 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.
