It was just a joke. A tasteless joke, but a joke.
Burger king CEO insults English women and this warrants a Wikinews article?
Family Guy and other shows on Television must have done this hundreds of times.
Meg: "You could murder all the girls prettier than me." Death: "No, that would just leave England"
As an American I don't get insults when somebody says Americans are fat. I know it's a stereotype and they aren't talking about me personally. (I weight about 80 Kgs and am 185 cm Tall). Furthermore, I think it's a hilarious joke.
English women being ugly is obviously the same thing. Look at girls like Kiera Knightly, Micha Barton, Kate Beckinsale, etc. etc. etc. It's a joke that's been around for a while and people should just get over it. It's said to be funny, not to offend. If you take something as offensive that was intended to entertain, then you perhaps need the attitude adjustment.
