This man died and was met by an angel who told him he would take him to
heaven.  The angel said he could bring one bag with him from earth.  This
man was a very frugal man and went to his home and looked around for
something to put in his bag.  He decided to fill it with gold bars he had
saved.
 
When he arrived at the Pearly Gates, St. Peter greeted him and invited him
in.  St. Peter them asked him if he had brought only one bag, and the man
responded: "Yes."
 
St. Peter asked to see what he brought.  So the man opened the bag and
showed St. Peter.  St. Peter looked puzzled and said to the man: "You
brought pavement?"
