Many years ago, KFC changed the way they cut up their chickens. Previously, they had taken a whole chicken breast and made three pieces out of it. Then they decided they would make two out of it, and had an ad campaign to let their customers know how much more they would get. My wife and I went in one day, and standing behind the counter was a well-endowed young woman displaying a large button which said...
"Our breasts are now 33% larger!"
I kept a straight face. Honest.
