Legendary office and computer pranks

Growing grass on a keyboard
Jaek Muran, a reader from Long Beach, pulled this brilliant prank on a vacationing colleague. Jaek took a spare, dead keyboard that was identical to the victim's, removed the keys, filled the keyboard with dirt, and planted "cat" grass. You can purchase "cat" grass from pet stores or the pet food isle of many grocery stores. It's thick and grows fast.

With the grass planted, Jaek covered the keyboard in plastic and kept it in sunlight or under a grow light. After 18 days, the grass had grown several inches and even uprooted a few keys.
