A farmer bought a beautiful dairy cow, a dappled black and white thing. He spent a hefty amount of money for the cow and bought it from a farmer friend in Michigan. The New Jersey farmer discovered that the cow farted crazily whenever it was hooked up to the milking machine. After several weeks of this gaseous ordeal, the farmer called in a bovine veterinarian to look over his prized animal.
After milking the cow by hand for a half hour, the farting was like an explosion and the stench was so horrendous the veterinarian vomited all over the barn.
"The cow's got to be from Michigan," the vet said, coughing and heaving.
"How did you know that I bought it from a farmer friend in Michigan?" the farmer said, bewildered.
"Well, my wife's originally from Michigan and whenever I suckle on her tits, she has the same problem," the vet hacked.
