<P> After the British version of the show ended its run, Mochrie joined the American version of Whose Line hosted by Drew Carey on ABC . He was brought on alongside Ryan Stiles, who was also a regular member of the UK cast . Mochrie appeared on every episode from its debut in August 1998 to its finale in 2006 . He noted his favourite games as "Scenes From a Hat", where he would have to act out scenes based on suggestions by audience members, and "Whose Line" where he and Stiles would act out a scene and have to add in lines written on pieces of paper . He felt that his weak spots were the musical segments and the "Hoedown" game, which he said was the only time during the show when he felt total fear . Mochrie, who cannot sing, usually spoke his lines instead of singing them . </P> <P> His co-stars on the show would frequently mock him for being Canadian and for his receding hairline, though this did not come until later as very early on in the UK version, Mochrie still had a fairly full head of hair . Instead, the bald jokes were done at the expense of the UK host, Clive Anderson . In the American version, he would often perform the female role in certain frequently - performed skits, such as "Whose Line" and "Two Line Vocabulary". In the few times he played the man in the scene, the producers were making further fun of his baldness (e.g. Colin was Samson, and Ryan was his girlfriend, and Samson had lost all his strength because Ryan had cut off his hair). While initially the co-anchor in the beginning, he would be cast as the anchor in the "Weird Newscasters" segment (the position had previously been played by Greg Proops and Brad Sherwood), wherein he would frequently begin by announcing himself with a fictitiously humorous name (e.g. Jose Canyousee) and continue with a fake news report that ended in an unexpected and pun - laden segue . </P> <P> According to his agent Jeff Andrews, during the airing of Whose Line Mochrie was better known in Canada as a "commercial king", performing as characters such the Detergent Crusader for Sunlight detergent . In March 2005, a Nabisco advertising campaign starred Mochrie as the "Snack Fairy", in which he wears a ballet tutu over ordinary slacks and a shirt . At the end of each commercial, he declares "Snack happy!" and waves his scepter while sporting a smile . </P> <P> Mochrie remained active elsewhere during his tenure as a Whose Line member . In early 1994, he played the role of Mike Brady in a musical version of The Brady Bunch, directed by fellow Second City member Bruce Pirrie . In the production, Mochrie plays the character as caffeine - fuelled, jittery, and neurotic, an exaggeration of the Mike Brady television character, who often had a coffee in his hand on the show . Shortly before his move to the US version of Whose Line in 1998, Mochrie starred in Supertown Challenge as the host of game shows, which the show spoofed . He also appeared in several episodes of the Canadian improvisational comedy series Improv Heaven and Hell . </P>
