I have done about all of these on David or friends at work (about 6 years ago). These are the easy things you can do to fool someone. I double dog dare ya to try just one.
|Put mayonnaise in doughnuts|
|Use duct tape to tape an airhorn to the wall where the door knob will hit it just right|
Then watch them scream
|Take the real deodorant out of the deodorant container and carefully replace it with cream cheese.|
Add a hair for emphasis then just wait.
|Use either colored tape or tape a small piece of paper to cover the laser on the mouse.|
I did this to David and it took him almost 15 minutes to figure out why the mouse wasn't moving.
|Tape an airhorn to the base of an office chair.|
Better yet, super glue the wheels of the chair to the floor. Don't use it on carpet.
If you want more super glue fun , glue dimes and nickels to the floor near a vending machine.
