Three guys get to heaven: Bob, Larry, and Bill. Before they enter, St. Peter warns them, “Whatever you do, don’t ever, ever step on a duck. Once one quacks, they all do, and they make a terrible racket.”
Bob enters heaven and immediately steps on a duck. An angel comes up to him and chains a large, hairy, ugly woman to him for eternity, saying, “I told you not to step on a duck.”
The next week, Larry steps on a duck. An angel comes to him and chains a very ugly woman to him for eternity, saying, “I told you not to step on a duck.”
Bill hadn’t stepped on a duck since he had gotten into heaven. Then one day, an angel comes up to him and chains a beautiful supermodel to him. He asked her why she was there, and she turned to him and said, “I don’t know what you did, but I stepped on a duck.”
