World's best engine

“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. It changes its own oil every four weeks. It is only a pity that the management system is so fucking temperamental."

Don't forget that sometimes it reproduces itself.

While they are dependable, it's been my experience that they are not very economical, and can be high maintenence at times. I have never found anything that I like better, so I guess I'll stick with them.
