It so happened that the equipment arrived when his wife was away. He decided to test it on himself first. He inserted his penis into the equipment, turned the switch on and voila, everything else was automatic!
He really had a good time as the equipment provided him with much pleasure. When the fun was over, he found that he could not take the machine off. He read the manual, but could not find any useful information. He tried every button on the instrument, but some made the machine squeeze, shake, or suck harder or less, but still latched on to his penis. Panicking, the farmer called the supplier’s Customer Service Hot Line.

The farmer: “Hello, I just bought a milking machine from your company. It worked fantastic, but how can I take it off from the cow’s udder?”
Customer Service: “Don’t you worry, sir. The machine was programmed such that it will release automatically after collecting a gallon of milk.”
