On vacation, Ole is at a bar in West Fargo when a man makes a bet wtih him, "I'll ask you a question...you get it right and I'll buy you a beer. Get it wrong and you owe me." Ole Agrees.
Guy says "My mother had a baby...it wasn't my sister...it wasn't my brother...so who was it?"
Ole thinks and thinks but can't get it. Guy says "It was ME stupid! Buy me a beer!"
Ole likes that one so the next time he's at the bar with Lars he makes the same bet. He asks Lars the same question ""My mother had a baby...it wasn't my sister...it wasn't my brother...so who was it?"
Ole thinks and thinks and finally answers, "Well, it was you Ole."
Ole says, "No stupid! It was some guy in West Fargo! You owe me a beer!"
