Three old friends pass away together in an accident and go to heaven.
When they arrive, St. Peter says, "We have only one rule here in Heaven... don't step on the ducks."
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, one of the friends accidentally steps on one.
Along comes St. Peter with the ugliest woman the man has ever seen.
St. Peter chains them together and says, "Your punishment for stepping on a duck is to spend eternity chained to this ugly woman!"
The next day, the second friend accidentally steps on a duck and along comes St. Peter, who doesn't miss a thing, and with him is another extremely ugly woman.
He chains them together with the same admonishment as for the first friend.
The third friend observes all this and not wanting to be chained for all eternity to an ugly woman, is very, VERY careful where he steps.
He manages to go months without stepping on any duck but one day St. Peter comes up to him with the most gorgeous woman he has ever laid eyes on... a very tall, tan, curvaceous, sexy blonde.
St. Peter chains them together without saying a word.
The man asks, "I wonder what I did to deserve being chained to you for all eternity?"
The women replies, "I don't know about you, but I stepped on a duck."
