Pardon me, I can’t hear you – Place a small piece of clear tape over the speaker part of the handset and watch the person get annoyed at the caller. For more fun remove the tape for a while then stick it back. Continue this on and off throughout the day.
The old flip screen routine – Click Ctrl+Alt+the down arrow and the display will flip vertically and the mouse controls with it. Impossible to get out of unless you know the shortcut which is the same, but with the up arrow instead.
Out of service – Put “Out of service” on all the toilet cubicle doors. Watch all of your colleagues run around. Why not add to the banter and put signs on the elevator doors as well.
Plastic wrapped doorway – Whether it’s the main door, your office door or the bathroom door, it can be hysterical watching a coworker bounce off! This prank is most effective in a dimly lit space to avoid glare spoiling the surprise. Sometimes just a strip waist high does the trick and goes most easily undetected.
Dead mouse – No, we’re not talking about killing any real animals here. For this April Fools office prank, position a sticker (or tape a piece of paper) under the mouse on their computer. Whether it’s a laser mouse or a ball-rolling mouse, the sticker will interfere with the mouse’s ability to work. Once they finally realize why their mouse isn’t working, they will look under their mouse and see the sticker or tape. Don’t forget to write “April Fools” on it.
Biggest fan in the office – Deck your coworker’s or boss’ office out in posters and fan gear from a celebrity they don’t really love.
Chair wrap – From foil to wrapping paper to toilet paper, decide on your material of choice for this April Fools office prank. Wrap your coworker’s chair completely, sneaking a Whooped Cushion under the wrap beforehand. When they walk in and see their chair wrapped, they’ll likely laugh and expect the joke is over… until they sit down on the hidden Whoopee Cushion.
