Sven found a printing press at a garage sale and decided to print some counterfeit money.  He printed up a batch and showed them to Ole.

Ole said, "You must be nuts!  Nobody vill take an eighteen dollar bill."

Sven said, "I know vere ve can det rid of dem... In Minn-ee-soda!"

Ole said, "Vel come on, ve'd better get rid of dem fast!"

They drive to a bait shop in Fergus Falls, pull out an eighteen dollar bill and ask the clerk, "You got change for dis her bill?"

The clerk, whose name was Lars, looks it over carefully and says, "You betcha!  Whaddya vant, two nines, or three sixes?"
