Former environment minister, former September 11 conspiracy theorist, leftwing thorn in the government's side and now candidate for the Labour leadership.
Michael Meacher is all these things and more, but, until now, his achievements had temporarily blocked out one of the most intriguing moments in his stellar career.
At the 2002 Labour conference in Blackpool, the Oldham MP took a 15-minute dip to fulfil a promise to go for a swim if the beach met European water standards.
So what happened next? Things just got more baffling.
As this picture by Getty's Scott Barbour shows, Mr Meacher and his two friends were soon joined by a fellow beachcomber dressed as a shark.
The media have been aching for a candidate to come forward to liven up the Labour succession, dominated as it is by the serious figure of Gordon Brown. Perhaps we've found him.
(I feel duty bound to echo here the caveats found at the end of stories about wacky private members' bills: Mr Meacher stands little chance of becoming leader.)
