XX - Milking Machine

A farmer orders an expensive milking machine. He decides to test it on
himself first, so he inserts his manhood into the equipment and turns
on the switch.

Soon he realizes that the equipment provides him with more pleasure
than his wife does..

But when the fun is over, he realizes that he cannot remove the
instrument from his tool, anxiously he reads the manual, but does not
find any useful information.

He tries every button on the instrument, without success.
Finally the farmer decides to call the customer hotline.
''Hello, I just bought a milking cow machine from your company, It
works fantastic, but how do I remove it from the cow's udder?''

''Don't worry sir'', replies the customer service person, ''the
machine will release automatically once it has collected two litres!"
