A farmer ordered a high-tech milking machine.

It happened that the equipment arrived when his wife was away.
So, 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 good time as the equipment provided him with as
much pleasure as his wife did. When the fun was over, he found
that he could not take the instrument off.

He read the manual, but did not find any useful information. He
tried every button on the instrument, some made the equipment
squeeze, shake, or suck harder or less, but still without
success.

Panicking, he 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 worry. The machine was programmed such
that it will release automatically after collecting about 2
litres of milk."
