(FWIW. “Sven and Ollie” are two yokels or hillbillies. They are popular subjects in Norwegian and Swedish jokes, often told in Minnesota and northern climates.. They typically are not the brightest bulbs on the Christmas tree.) …
…
Sven and Ollie buy a mule. But when they get it home, they can’t get it into the barn. It just won’t go.
Sven says, “I know just the problem. He won’t fit through the door because his ears are too long.”
Ollie sees that Sven is right, thinks a bit, and then says, “I know what we can do. We should raise the barn up by a foot, so he’ll fit.”
Sven asks, “Wouldn’t it be easier to dig a ditch for him to walk in?”
Ollie says, “Sven, don’t be such a duммy! It’s his ears that are too long, not his legs!”
