An Arkansas farmer ordered a super-duper high-tech milking machine for his cows. It just so happened that the equipment arrived when his wife was in town shopping. So, he decided to test it on himself first. He inserted his manlyhood into the equipment, turned the switch on and -- voila -- everthing else was automatic!
He really had a good time. The equipment provided him with as much erotic pleasure as his wife did. When the fun was over, he found that he was unable to turn off the milking machine.
He sat there, next to the mooing cows, reading 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 sucess.
Panicking, he called the supplier's Customer Service Hot Line...
"Hello," said the farmer. "I just bought one of those fancy milking machines from your company. It worked fantastic. But how can I take it off from the cow's udder?"
The customer service representative said, "Don't worry. The machine was pre-programmed so that it will release automatically after collecting two gallons of milk."
