Jensen is in the dairy business, and hears his neighbor just got a prize winning milk cow, so he goes over to visit. As luck would have it, he finds Smith in the barn looking over the latest addition to the herd.
Thats one fine beast ya got there, Smith, says Jensen.
Oh, yah, replys Smith. Not only is she pretty, but she give the sweetest milk, and the cream just floats to the top. Oh and the amount; sure it was a bargain.
Well, says Jensen, thats pretty good, but theyve all got some fault.
Oh, sure, theres one. Its kinda strange though; I never seen nothing like it before. And Smith pulls over his stool and a bucket, and reaches down under and grabs a teat. He gives it a pull, directing a stream of milk into the pail, but as he does the cow lifts her tail and lets out a monster fart. Smith reaches over and pulls another teat, with the same result.
Now what do you think of that?, he asks. Ive been farming 50 years and never seen nothing like that.
Jensen is quiet for a minute, and then he asks, This cow, did you get her over in Iowa?
Yes, says Smith, I did. How would you know that?
Jensen rubs his head and replies, You know my wife
Yes, of course
You know shes from Iowa
I seem to remember that, yes
Well, she does the same thing.
