In 2003, he broke 383 year-old World Record by paddling an 85 per cent paper boat 160 miles down the River Thames to raise money for Comic Relief, which earned him the freedom of the City of London.
The following year he tried to cross the Channel in a bathtub - but the attempt was called off after 20 miles due to a force 6 storm. Undeterred, he tried again in 2005, successfully arriving at Tower Bridge after a 130-mile row. Thomas Crapper and Co. released a lavatory named The Honorable FitzHigham to celebrate the journey - the company's second ever commemorative lavatory in history; the other commemorating Queen Victoria's jubilee.
In Trafalgar Square in 2006 he tried to to erect the world's longest clothes line for World Environment Day, but the attempt failed. However, his attempts to emulate Cervantes's hero Don Quixote were more successful, and he was appointed Most Puissant Knight de Santa Maria in the West Indies and the 650-year-old title Pittancer of Selby Town in the West Riding, North Yorkshire.
Aways from his adventures, FitzHigham has toured extensively with the Flanders & Swann tribute show At the Drop of a Hippopotamu from 2001 to the present, and played the Dauphin in a touring production on Henry V.
One of his first tastes of comedy was as part of London's topical Newsrevue team in 1999.
