April Fool's Day in the Workplace

With April Fools' Day falling on a Saturday this year, the whoopie cushions and fake vomit may find their way into the workplace a day earlier.

According to a survey by CareerBuilder.com, 33 percent of workers admit to having played a practical joke on a coworker in years past and 17 percent say they'll do it this time around, too.

Among the top-ten pranks people play on their co-workers: changing the caller ID on a co-worker's phone to read Mr. Kitten, putting random objects from people's desks in the vending machine and placing rubber chocolates in the break room and watching as coworkers try to chew them.
