step one:
get your nipples pierced.

step two:
attach key ring to nipple piercing.

step three:
Tie the cord to the key ring then attach the cord to a memory stick. Make sure you can't untie the usb stick from the cords.


Now when ever you walk away from the pc you will be reminded by a sharp pain from your tender nipples.

Don't worry god gave you two for a reason. :P
