Ryan Stiles

By 1989, Stiles had gained the attention of the producers of the British improvisational comedy show Whose Line Is It Anyway? Stiles was a regular on the show until its end in 1998. His performance on the program earned him both critical praise and a devoted fan following in the United Kingdom. In 1995, Stiles was asked by American comic Drew Carey to be a regular on his comedy The Drew Carey Show. Stiles played Carey's erudite but underachieving best friend, Lewis Kiniski.

In 1998, Carey successfully lobbied ABC to produce an American version of Whose Line Is It Anyway? Following the final season of the British version in 1998, the American version premiered, with both Stiles and Carey credited as executive producers. Stiles and Colin Mochrie were the only two performers to appear in every episode of the US version, although Wayne Brady also became a regular near the beginning of the second season. The series was produced until 2006. Stiles received a nomination for a Primetime Emmy Award for Individual Performance in a Variety or Music Program in 2002 for his work on the show. A running gag of the show is Stiles' flashy dress shoes.

Though he never appeared in the series, Stiles (along with Kaitlin Olson) performed in the taping of the unaired pilot episode of Drew Carey's Green Screen Show, which involved improv games similar to Whose Line? games played in front of a massive green screen. Animation was later added to the improv footage.

Stiles returned as performer and executive producer for The CW's revival of Whose Line Is It Anyway? in the summer of 2013.[1]

Stiles appeared in the 1991 film Hot Shots! as Mailman Farnham and starred in its 1993 sequel, Hot Shots! Part Deux, as marine Rabinowitz. He portrayed recurring character Dr. Herb Melnick on Two and a Half Men from 2004 until the show's end in 2015. He made short guest appearances on Parker Lewis Can't Lose, Murphy Brown, Mad About You, Mad TV, and Dharma & Greg. In July 2008, he was a guest star on Reno 911! as Sergeant Clift, an acting coach.

During the 1994 Major League Baseball strike, Stiles appeared in several commercials for Nike, hanging out in an empty ballpark, doing things such as playing the organ and attempting to do the wave alone. The commercials ended with the line: "Play ball. Please."

In 2005, Stiles appeared in the mockumentary Conker: Celebrity Squirrel produced for the promotion of the Xbox video game Conker: Live & Reloaded.[2] This role led to gamers voting to induct him into the 2015 class of the DK Vine Hall of Fame.[3]
