Sitting  on the side of the highway waiting to catch speeding drivers, a Police Officer  sees a car puttering along at 22 KPH.
Says  he to himself: "This driver is just as dangerous as a  speeder!"
So  he turns on his lights and pulls the driver over.
Approaching  the car, he notices that there are five old ladies, 
Two in the front seat and  three in the back...wide eyed and white as ghosts.
The driver,  obviously confused, says to him "Officer, I don't understand, I was doing  exactly the speed limit! What seems to be the problem?"
"Ma'am," the  officer replies," you weren't speeding, but you should know that driving  slower than the  speed limit can also be a danger to other drivers."
"Slower than the speed  limit? No sir, I was doing the speed limit exactly...Twenty-two kilometers an  hour!"  ...the  old woman says a bit proudly. 
The Police officer, trying  to contain a chuckle explains to her that 22 is the highway number, not the  speed limit.
A bit embarrassed, the woman grins and thanks the officer  for pointing out her error.
"But before I let you go, Ma'am, I have to  ask....Is everyone in this car OK?  These  women seem awfully shaken, and they haven't made a peep this whole time," the  officer asks.
"Oh, they'll be all right in a minute officer. We just  got off Highway 189.."

Do you know what would have happened if it had been Three Wise Women instead of Three Wise Men?
They would have asked for directions,
Arrived on Time,
Helped deliver the Baby,
Cleaned the stable,
Made a casserole,
Brought practical gifts, and
There would be Peace on Earth.
