on the show, in 2010. Carey usually promotes Kinney's next project during the closing of that episode.) Lewis Kiniski (Ryan Stiles) – Forms a double-act with Oswald. Lewis, who is tall, gangly, and perpetually bemused. Ryan Stiles once described Lewis as "Not even a character at first, just a creep really." He possesses an IQ of 162, but works as a janitor for a company called DrugCo, which conducts bizarre experiments. Due to accidentally releasing a strain of bacteria into the population, he was busted down to janitor from a position that required him to wear a lab coat. At one point, he posed as Drew to take his physical exam for him, unexpectedly taking a psychiatric exam as well. He tried to give answers which he thought suited Drew's life and situation, and the results showed him to be mentally unstable and possibly criminally insane. He mentioned in one episode he was adopted. Oswald Lee Harvey (Diedrich Bader) – Lewis's slightly shorter, dark-haired friend is the dumb one of the double-act, which tends to be his most distinguishing characteristic. Lewis described him once as a "man-child stuck in a sort of prolonged adolescence." Oswald was a deejay at the beginning of the first season but later on became a delivery driver for Global Parcel (a fictional package-delivery service whose uniforms are modeled after those of UPS). He later attempted to become a nurse, but he failed the required tests. Drew later got him a job as a delivery man for Never Ending Store, but Oswald was injured on store property. After receiving damages, he bought the Warsaw. In the episode Bus-ted, it is revealed that Oswald joined the group of friends to replace Adam, a childhood friend who fell through the ice on a lake. Aside from Carey, Bader is the only cast member to appear in every episode of the series. The name of Bader's character is an obvious reference to Lee Harvey Oswald, the gunman who assassinated President John F. Kennedy. Kate O'Brien (Christa Miller) – Friends with Drew, Lewis, and Oswald since they were kids. Kate is a bit of a tomboy and a hothead and good with her fists. She and Oswald almost got married at one point, but she called it off just after Oswald threw her a surprise wedding (essentially leaving Oswald at the altar). She later found out about Drew's long-standing crush
