ABC's surprise summer hit, "Whose Line Is It, Anyway? " (8:30 tonight on Channel 9), should come as no surprise to anyone who has seen Ryan Stiles of "The Drew Carey Show" and the show's other comedic panelists perform hysterical improvised routines on a moment's notice. One of the reasons the show works is that it immediately follows the sitcom featuring Stiles and "Whose Line" host Carey, and it lets us see both men play against their characters on "Drew Carey. " You never see Stiles' lightning-quick mind on "Drew Carey," where he's the slow-witted Lewis. And lovable loser Carey is a winning emcee here.
