Ole and Sven

Ole and Sven are neighbors in Minnesota. Ole is in need of a new milk cow. He hears about a nice one for sale over the border in Wisconsin. He drives over to Wisconsin, looks at the cow, and reaches under to see if she gives milk. When he grabs the teat and pulls, the cow farts. Ole is very surprised, looks at the farmer who is selling the cow, and reaches under the cow to try again. He grabs another teat, pulls, and the cow farts again. Milk does come out, however, so after some discussion, Ole decides to buy the cow anyway and take it home. He calls over his neighbor, Sven, and says, "Come here and look at dis new cow I yust
bought. Pull her teat and see vat happens dere." Sven reaches under and pulls; the cow farts. Sven looks at Ole and says, "You bought dis cow over dere in Visconsin, yah?" Ole is very surprised and says, "Yah, dats right, how did you know dat?" Sven says, "My vife is from Visconsin!"
