                                                        OH, TO BE TEN AGAIN

                        A man asked his wife, "What would you most like for your birthday?"

                        She said, "I'd love to be ten again."

                        On the morning of her birthday, he got her up bright and early and
                        off they went to a theme park.

                        He put her on every ride in the park--the Death Slide, The Screaming
                        Loop, the Wall of Fear. Everything there was, she had a go.

                        She staggered out of the theme park five hours later, her head
                        reeling and her stomach upside down.

                        Into McDonalds they went, where she was given a Double Big Mac with
                        extra fries and a strawberry shake.

                        Then off to a theater to see Star Wars--more burgers, popcorn, cola
                        and sweets.

                        At last she staggered home with her husband and collapsed into bed.

                        Her husband leaned over and asked, "Well, dear, what was it like
                        being ten again?"

                        One eye opened and she groaned, "Actually I meant dress size."
