Here's an Ole and Lena joke. You have to live in my part of the country (Minnesota, WI, the Dakota's) to appreciate this joke.

Lena and her husband Ole go to a bar and meet Sven. After a few hours of drinking, Lena and Sven disappear. So Ole ask's the bar tender- "have you seen Lena?" The bar tender replies- "I saw her step outside with Sven a little while ago." So Ole steps outside and see's Lena and Sven having sex in the back seat of his car. Ole walks back into the bar and orders and beer. The bar tender asks- "Did you find her?" Ole replies- "She was in the back seat of my car making love to Sven." "Aren't you going to do something" the bar tender replies.

So Ole says-"No, that Sven, he just thinks he's me!"
