Richard Hammond was the main presenter of Brainiac: Sciene Abuse from Series 1 to Series 4. He started each part of the show with a joke starting with: "This is Brainiac, the science show that..." He took part in some experiments, many involving Co2 powered vehicles. He quit in series 4 before his Vampire crash and resumed working with BBCTwo on Top Gear and Vic Reeves took over from him.
