A man asked his wife...
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 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. She had a go on every ride there was. She staggered out of the theme park five hours later, her head reeling and her stomach turning. Then off to a movie theater, 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, honey, I meant dress size!"
She said, "I'd love to be ten again."
