Ole is a farmer in Minnesota . He is in need of a new milk cow and hears about a nice one for sale over in Nortdakota (that would be ' North Dakota ' for the non-Scandinavians out there). He drives to Nortdakota, finds the farm and takes a look at the cow. Then he reaches under to see if she gives milk.
When he grabs the teat and pulls ..... the cow farts.
Ole pauses, looks at the farmer who is selling the cow, and reaches under the cow to try again. He grabs another teat and pulls ... and the cow farts again.
Milk does come out however, so after a brief negotiation with the cow's current owner, Ole decides to buy the cow and take it home.
When he gets back to Minnesota , he calls over his neighbor, Sven, and says, "Hey, Sven, c ome and look at dis here new cow I yust bought. Pull her teat, and see vat happens."
Sven reaches under, pulls the teat - and the cow farts.
Sven looks at Ole and says, "You bought dis here cow in Nortdakota, didn't yah?"
Ole is surprised since he hadn't told Sven about his trip and replies, "Yah, dat's right, but how did you know?"
Sven says, "My wife is from Nortdakota."
