Today i decided to do routine maintenance of my computer: My random whenever I have time cleaning of the inside with pressurized air. After my computer was all plugged in and booted up I reached for the mouse to log in. Except the cursor did not move. Panicked I starting checking the cords and stuff and then realized maybe something is on the laser. I turned the mouse over and there was a sticky note that said "You just got pranked" Thanks little sis. I thought something was seriously wrong.
