When I was a senior in Vet College a bunch of us went out on a routine farm call doing vaccinations on a Holstein dairy herd. The herd was gathered around the milking barn and since all the animals this barn twice a day, they were used to entering the corridors and standing quietly. After a couple of hundred times of lifting the tail, inserting the thermometer, reading the ear tag number, cleaning some rump skin, and jabbing in 3 syringes of vaccine it got a bit routine and boring.

Until suddenly I noticed that the rump I was behind was about a foot higher, about a foot wider, and instead of a 4 titted bag down there, there was a huge scrotum. Then Mr. Bull turned his head and looked back at me as if to say, "Let's be careful today, right?"
