It took me a good 10 minutes to figure it out! That moment reminded me how harmless, funny pranks can really lift the mood — especially if your workplace thrives on creativity. Small spaces — even desks — can inspire big ideas. Today, I’m sharing 10 April Fools prank ideas I’ve tested, tweaked, or witnessed in the office.1.
