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 ... viola,
everything else was automatic!!

He really had good time as the equipment provided him with much pleasure. 
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 
asks:  "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 liters of milk.
