The penis knows where it is at all times. It knows this because it knows where it isn’t. By subtracting where it is from where it isn’t, or where it isn’t from where it is (whichever is greater), it obtains a difference, or deviation from the balls The guidance cum system uses deviations to generate corrective cockmands to drive the penis from a position where it is to a position where it isn’t, and arriving at a position where it wasn’t, it now is. Consequently, the position where it is next to the balls, is now the position that it wasn’t, and it follows that the position that it was next to the balls, is now the position that it isn’t. In the event that the position that it is in is not the position that it wasn’t, the penis has acquired a virus, the virus being the difference between where the missile is, and where the balls are. If the virus is considered to be a significant disease, it too may be chopped off along with the balls. However, the penis must also know where the balls rest in relation to itself.
