Richard Mark Hammond, nicknamed "Hamster", (born 19 December 1969)  

Richard Mark Hammond, nicknamed "Hamster" is an English broadcaster, writer and journalist most noted for co-hosting car programme Top Gear with Jeremy Clarkson and James May, as well as presenting Brainiac: Science Abuse on Sky 1 and Sky 3, Richard Hammond's Engineering Connections on BBC Two, Should I Worry About...? on BBC One, Total Wipeout, also on BBC One and Richard Hammond's Blast Lab on CBBC. He has also presented several one-off specials such as ITV's The Gunpowder Plot: Exploding The Legend and the annual Crufts awards.

Hammond became a presenter on Top Gear in 2002, when the show began its present format. He is sometimes referred to as "Hamster" by fans and his co-presenters (Jeremy Clarkson and James May) on Top Gear due to his comparatively small stature. His nickname was further reinforced when on three separate occasions in Series 7, Hammond ate cardboard, mimicking hamster-like behaviour. Another running gag by co-host Jeremy Clarkson is Hammond's supposed use of teeth whitener, and it was staged to appear that he was caught looking at a website on teeth whiteners on Richard Hammond's 5 O'Clock Show. Clarkson had found a pack of teeth whiteners in the Marcos TSO GT2 Hammond had tested. Hammond had objected, saying it was a set-up. During an episode in June 2009 which featured the presenters in their office searching for car insurance prices while pretending to be 17 year olds, a teeth whitening kit was pictured on his desk. When the Peel P50 was being tested in the Top Gear office, Jeremy Clarkson was supposedly talking to Hammond on the phone about him whitening his teeth for 4000 .....
