(Sven and Ollie are mainstays of Norwegian and Swedish jokes, often told in Minnesota and northern climates. They typically are not the brightest bulbs on the Christmas tree.) …

Sven’s down at the feed store and runs across Ollie.
Sven says, “Ollie, good to see you! How’ve you been?”
“Fine.”
“And what about your wife, I haven’t seen her in awhile. How’s she doing, Ollie?”
“Fine.”
Sven says, “I heard you bought her a piano, didn’t you? That must be real fine. How’d she like it?”
Ollie answers, “Fine. But I sold the piano and bought her a clarinet.”
“A clarinet? Why would you give her a clarinet instead of a piano?”
Ollie glares at Sven a bit, then says, “Because with a clarinet, she can’t sing!”
