A high-tech milking machine

farmer ordered a high-tech milking machine. Since the equipment arrived when his wife was out of town, he decided to test it on himself first. So, he inserted his "manhood" into the equipment, turned on the switch and everything else was automatic. Soon, he realized that the equipment provided him with much more pleasure than his wife did. When the fun was over, though, he quickly realized that he couldn't remove the instrument from his 'member'. He read the manual but didn't find any useful information on how to disengage himself. He tried every button on the instrument, but still without success. Finally, he decided to call the supplier's Customer Service Hot Line with his cell phone (Thank god for cell phones!). "Hello, I just bought a milking machine from your company. It works fantastic, but how do I remove it from the cow's udder?" "Don't worry," replied the customer service rep, "The machine will release automatically once it's collected two gallons." Have a nice day.....
