Sven came over to help Ole put new siding on his house. They put on their nail aprons and grabbed their hammers.
After a while, Ole noticed Sven doing something strange. Every once in a while Sven would pull a nail out of his apron and put it up to the siding. Instead of pounding it in he would throw it over his shoulder.
Ole said, "Hey Sven,what are you doing that for?"
Sven replied, "Some of these nails is broke. Da head is on da wrong end."
Ole replied, "No-No Sven, dem nails is fer da udder side of da house."
