Colin Mochrie was a regular improviser on Whose Line is it Anyway. Colin started on the UK version of Whose Line during its third series, gradually appearing more often until he became a regular during the eighth season. His success led him to apear in all 220 episodes of the US version.
Colin is best known for his deadpan, his ability to think quickly during a sketch and for his complete randomeness. He would often use puns, especially when playing the anchor on Weird Newscasters.
Cast members often made jokes about baldness at Colin's expense, as well as the fact that he is from Canada.
