Some people don't care for them, but I love Ole and Lena jokes. 

Here's a good one. 

Ole was going on a business trip to St Cloud but it was cancelled at the last minute cause the Minnesota Twins made it to the playoffs.  

He's lying in bed before going to sleep when the phone rings. 

He listens, gets up to look out the window then returns to the phone. 

He says in an irritated way: "How should I know, it's a thousand miles away!" and hangs up. 

Lena asks: Who was that Ole? 

Ole: Oh Sven yust vants to know if the coast is clear.
