Australian swimmer Ian Thorpe is the surprise star of the BBC's London 2012 coverage so far, taking pride of place on the studio sofa to comment on events.
But how much do you know about the medal winning Olympian? Here's five things you probably didn't know about man they call the Thorpedo.
1) He takes the tube
Courtesy of Thorpe's official Facebook page, here's a picture of his "commuter impression." As his fans commented, he could try looking a little more angry.
2) He's allergic to chlorine
During his early years Thorpe struggled when he was allergic to chlorine - despite having the "perfect swimmers body". He later overcame the setback to become one of Australia's most successful athletes.
3) He's struggled with his weight
Despite being an Olympic champion, Thorpe has struggled with fitness in the past. Here's a pic of the Olympic champion after he retired - and before he got back in shape.
4) He's a philanthropist
He founded Ian Thorpe's Fountain for Youth in 2000, which sponsors a school for orphans with disabilities in Bejiing, and also works to improve living standards in aboriginal communities in his home country.
5) He's earning $10,000 dollars a day (possibly)
According to the Sydney Morning Hearld, he earns $10,000 Australian dollars a day - or £6,735 pounds - for his role "baffling the Brits" on the BBC.
