Oscar Wrigley, a two-year-old with the same IQ as Albert Einstein and Stephen Hawking, has become the youngest boy in Britain to be accepted into Mensa. He has been ranked in the 99.99th percentile of the population and has been ranked off the scale as the Stanford-Binet test cannot measure higher than 160.

Oscar’s father Joe, 29, an IT specialist from Reading in Berkshire, said: “Oscar was recently telling my wife about the reproductive cycle of penguins. I’m fully expecting the day to come when he turns around and tells me I’m an idiot.”
