An elderly farmer decides he's had enough of milking his cows by hand so he decides to invest some money in an electronic, industrial milking machine. After a couple of days his new 'state of the art' device arrives. He waits around until his wife is out for the day and decides to test the machine on himself. Once its installed he pops his pecker into the 'udder sucker' and switches the machine on. After having the best orgasm of his life old boy decides he better switch the machine off and get his pants back on, it's then he realises he's stuck in the machine. After trying everything he could think to release himself he decides to call the customer service helpline. "Hello," he says, "I've recently purchased a milking machine from your good selves. It works just fine, but i was wondering how you remove it from the cow's udder?"
"Don't worry sir, this is state of the art technology." Replies the salesman, "The device will release automatically once it's collected 2 gallons."
