A farmer needed to castrate his bull.
After a search of many options including the local veternarians he decides to go with the guy with the cheapest price. The next day a man shows up with a briefcase and opens it and the farmer is surprised at what’s inside. The fellow pulls two bricks from the case and explains that he will go to the rear of the bull and with one brick in his left hand and the other one in his right he will smash the bull’s testicles by banging the bricks together. “Holy shit!” the farmer says “won’t that hurt like hell?!!! “nah” the man says… “you just got to make sure you keep your thumbs on the outside”
