Step 2: Preparing The Prank.
=Now, go to your computer.
=Get one sticky note and rip it up into four pieces so that two pieces have some sticky stuff on them.
=Place one of the sticky pieces on the bottom of the mouse, so that the infrared beam is covered.
=Now, before you flee from the scene of the crime, test it out if the computer is on. If it works, ta-daa!
=If not, place the other sticky piece over the other sticky not on the bottom so that there is absolutely NO chance the sticky note will fold and let the beam through!
