The Perfect Machine - PG17

A notable gynecologist once said:
"The best engine in the world is the Vagina.
It can be started with one finger.
It is self lubricating.
It takes any size piston.
And it changes its own oil every four weeks.
It is only a pity that the management system is so temperamental..!"

Tony adds:

The worst machine is the Dick (many famous Dicks like Cheney...).
It has to be started with 5 fingers.
It is not self lubricating.
If it does not fit, there is no benefit.
It only works for 2 minutes and takes a break for 6 days.
It is very easy to be damaged and there is no part for repair.
It costs the owner to operate, just opposite than Vagina.
If not properly used, it will cause lawsuit and even kill the owner.
The list is endless.
