Top 10 April Fools Day Office Pranks

29 percent of workers say they have either initiated or been on the receiving end of an April Fool's Day prank at work. This is
according to CareerBuilder.com's annual April Fool's Day survey, which was completed in March 2007 and included more than 6,800 workers.

While covering someone's cube with aluminum foil, faking a resignation or gluing office supplies to the desk continue to be among the most common
pranks, CareerBuilder.com has named the top ten most memorable capers uncovered in this year's survey:

  1.  Sent a letter signed by the president of the company that informed
      employees they would have to take potty breaks in alphabetical order.
  2.  Decreased the size of boss's lab coat. Joke continued after April 1
      with boss perplexed by his coats getting tighter each week while he
      was dieting so diligently.
  3.  Made for a very foggy day with dry ice in the urinal.
  4.  Changed all of boss's reading glasses to clear glass.
  5.  Sent a note to co-worker's pager that said to contact "George." The
      number was to the White House.
  6.  Employee went to the restroom and when he came out, he ran into a wall
      of tape draped across the doorway, courtesy of his team.
  7.  Put "random burping" program on boss's computer that would loudly burp
      every few seconds -- it went on for days.
  8.  Brought in jelly doughnuts filled with ketchup.
  9.  Had someone with a "questionable" profession call the office and ask
      for directions.
  10. CEO placed a very large and official-looking "For Sale" sign in front
      of the building.
