I related to my colleague a funny anecdote. The hero of anecdote was both a he-goat and the milking machine for it. He told the real story. September 1969. 1st year students of the 1st Medical Institute, like all the intellectual forces of the Soviet country, as usual were sent to harvest. They dug potatoes. Location - the Chekhov district of the Moscow region, village Zykeevo. Picturesque, I must say the place. The excess energy with a lack of the usual food stirred the imagination of future doctors. They wanted to drink goat's milk. The source of it, they believed, not far quietly grazing. The animal was covered with thick, long hair. He was tied to a tree, horns firmly pulled strong rope. My colleague heard somewhere that it increases milk yield. They begin the process of milking. Milker long pulled the two hanging almost to the ground and waited for the appearance of the nipple milk. But there was no milk. Future doctors were puzzled, while the locals, who watched the progress of the process, laughing heartily. The nanny goat was a he-goat, and his enormous testicles students took as the teats of udder.
