I play little games at work sometimes. One of them is Urinal Ninja. Can you use it without tripping the sensor? I can.
What games do you play?
Note on Urinal Ninja, which I can sense will be the next internet craze sweeping college dorms everywhere: The ninja must be close enough to use the urinal normally (no ten foot arcs splashing on the floor) but also in such a way as to not trip the sensor. Sideways, from the ceiling, etc. If you make a mess for the custodial staff, you lose.
