THE OFFICE — What's the best office prank you've ever seen? Maybe someone gift-wrapped your desk or put your stapler in Jell-O. Or perhaps it was a more subtle trick, like switching out your family ...

Pranking a server might be fun from the customer’s point of view, but for the employee, it isn’t always a laughing matter.

Cut out a tiny protest sign that says, “I refuse to work today! -Your Mouse,” and tape it over the sensor. Make this office prank funnier by adding tiny stick-figure co-workers picketing next to it.
