Sven was going for his morning walk one day when he walked past Ole's house and saw a sign that said, "Boat For Sale."

This confused Sven because he knew that Ole didn't own a boat, so he finally decided to go in and ask Ole about it.

"Hey Ole," said Sven, "I noticed da sign in your yard dat says, 'Boat For Sale', but ya don't even have a boat. All ya have is your ol' John Deere tractor and combine."

Ole replied "Yup, and they're boat for sale."
