The youngest boy and youngest member ever accepted was Ben Woods, who joined Mensa in the 1990s at 1,035 days old, according to Mensa's Web site.

British Bombshells

Boyle became the instant favorite to win the television competition. Soon her face appeared on tabloids and television shows around the world.

Then on the same popular British TV show where "American Idol's" Simon Cowell serves as a judge, 12-year-old Shaheen Jafargholi wowed audiences with his bombastic pipes.

The trio is helping to make a big splash outside its native United Kingdom. It leaves some to wonder just how much talent does Britain have?
