There are these three blondes stood on one side of the river one day, wondering how they’re going to get across to the other side.
The first blonde, in desperation, begins to pray, “God please make me smart enough to get across this river.”
God hears this and turns her into a brunette and she swims across the river.
The second blonde then also starts to pray, saying, “Dear God, please make me twice as smart as the last girl so I can get across this river.”
So God turns her into a redhead and she builds a boat and rows across the river.
The third blonde, seeing this, also start to pray. She says, “Dear God, please make me twice as smart as both of those women combined.”
So God turns her into a man and she walks across the bridge.
