So they enter heaven, and sure enough, there are ducks all over the place. It is almost impossible not to step on a duck, and although they try their best to avoid them, the first woman accidentally steps on one.
St. Peter comes along with the ugliest man she ever saw and chains them together and says, "Your punishment for stepping on a duck is to spend eternity chained to this ugly man!"
The next day, the second woman accidentally steps on a duck and along comes St. Peter, who doesn't miss a thing. With him is another extremely ugly man. He chains them together with the same admonishment as the first woman.
The third woman has observed all this and, not wanting to be chained for all eternity to an ugly man, is very, VERY careful where she steps. She manages to go months without stepping on any ducks, but one day St. Peter comes along and he is chained to the most gorgeous man she has ever seen.
St. Peter says to the woman, "You have been very good and have avoided stepping on ducks, so I will allow you to be chained to this very handsome man for all eternity!"
The woman happily accepts her fate and, feeling pleased with herself, looks over at the man she is chained to and says, "I wonder what I did to deserve being chained to you for all eternity?"
The man looks at her and says, "I don't know about you, but I stepped on a duck!"
