 Ryan Stiles won the role of "hapless janitor" Lewis Kiniski. Despite being well known for his role on the British improve show Whose Line Is It Anyway?, Stiles still had to go through the audition process along with everybody else. He said, "I don 't even think Drew was really even aware of Whose Line at that time because it hadn't been on the air (in the U.S.) that many years. I think it was only on Comedy Central at that time." Stiles admitted that he liked to have fun with his character and not psychoanalyze him. Following his appearance in The Beverly Hillbillies, Diedrich Bader realised he needed a regular income and decided to return to television. He tested out for The Drew Carey Show, but did not initially want to be cast in it. He told Kevin Smith that he wanted to drive up his price for the pilot of Partners. Bader lost out on the role of Bob to Jon Cryer and then learned The Drew Carey Show wanted to hire him to play Oswald Lee Harvey.
