In the north of China under the Gobi desert mil doctors travel around giving the snip to men with two children or more. They are accompanied by interpreters. One day a doctor saw a chap with two children in tow. "Over here" he shouted. The man was questioned to why he had two children. he said he "didn't know." He was escorted to the doctors office and given a lecture and issued with some condoms. "Wear these and it won't happen again" said the doc. A year later he saw the same man this time with three children. He was questioned via the interpreter. There was some mumbling and the interpreter explained to the doc. "He said he did wear it for about three days, but he was busting for a piss, so he cut the end off it"
