England's royal family frequently is the butt of jokes.
But the rear end of Prince William's sister-in-law, Pippa, is no joke. It's an international phenomenon.
The derriere of Philippa Middleton, Kate's only sister, has spawned thousands of fans in Facebook and other websites.
And spurred a 60 percent boom in requests for "bottom-enhancement" procedures in Britain and elsewhere.
Pippa stole the limelight as the maid of honor during the recent wedding of the Duke and Duchess of Cambridge.
While millions of female viewers admired her Alexander McQueen gown, millions of male viewers admired Pippa's bum as she carried Kate's bridal train into Westminster Abbey.
Visit one of the fansites, Pippa Middleton Ass Appreciation Society. It's rather cheeky. (29 MAY 2011)
