Three guys did in a car wreck and they all go to heaven.

Saint Peter meets them at the gate and tells them there is only one rule in heaven. Don't step on the ducks. And when they got inside they saw the place flooded with ducks. Well the first day one guy steps on a duck. St Peter comes along with a very ugly woman and chains them together. For stepping on a duck you will remain chained to an ugly girl for eternity.
Well next day the next guy steps on a duck and along comes St Peter with an ugly girl and chains them together and your punishment for stepping on a duck is remaining chained to an ugly girl for eternity.
Needless to say the last guy is real careful and months later along comes St Peter with the most beautiful woman he ever saw and he was chained to her. And he said what did I do to deserve this and the woman says I don't know about but I stepped on a duck.
