But the Blank Park Zoo in Des Moines, Iowa, is ready for April Fools' Day pranksters.
The zoo has set up hotlines for people to phone "Mr. Albert Ross," "Mr. C. Lyon," "Ms. Anna Conda," and, or course, "Mr. Don Key."
Each number has a recorded message letting callers know they've been had.
Zoo marketing director Ryan Bickel says they want to keep the zoo's switchboard from getting flooded, without being a kill-joy.
