Ah, Sven and Ole jokes. My dad was from Minnesota, so I heard a lot of them.
My own favorite: After years of being courted by both Sven and Ole, Lena decided to marry Ole. At the party after the wedding, Ole discovers Sven and Lena having sex in the back bedroom. Ole is laughing uproariously, and the other guests try to calm him down, saying, “Take it easy, Ole, you’re drunk and you don’t want to do anything you’ll regret later.” Ole, still laughing, says, “I’m drunk? Look at Sven! He’s so drunk, he thinks he’s me!”
