He drives to Nordakota, finds the farm and looks at the cow.
He reaches under to see if she gives milk. When he grabs the tit and pulls, the cow farts. Ole is surprised
He looks at the farmer selling the cow, then reaches under the cow to try again. He grabs another tit, pulls, and the cow farts again. Milk does come out however, so after some discussion, Ole buys the cow and takes her home.
He gets back to Minnesota, and calls over his neighbor Jimmy Mooney,and says, “Jimmy, come look at dis ere new cow I yust bought. Pull her tit, and see vat happens.”
So Jimmy reaches under, pulls the tit – and the cow farts. Jimmy looks at Ole and sez, “You bought dis here cow in Nordakota, din’tyah?”
Ole is surprised since he hadn’t told Jimmy about his trip. Ole replies, “Yah, dats right. But how’d yah know?”
Jimmy says, “My wife’s from Nordakota.”
