April Fools' Day Work Pranks: Silly, Stupid And Sometimes Vicious

Each year around this time, workers at the Como Zoo in St. Paul, Minn., endure a flood of calls from pranksters looking to speak with Al E. Gator, Billy Goat and other assorted fictitious folks who just happen to have animal-themed names.

Last year, the park handled 300 such calls in one day, so this year zoo officials decided to add four phone lines to handle the increased call volume it's anticipating this April Fools' Day, St. Paul's Pioneer Press reports.
