Bill Maher, another veteran comic, hosted "Politically Incorrect" on Comedy Central from 1993 until 1997, when the show moved to ABC. It was canceled in 2002 after controversial comments were made on the show following the 9/11 terrorist attacks. HBO's "Real Time With Bill Maher" now airs on Fridays and features interviews and panel discussions with prominent political and media figures, and Maher's comic monologues. But "Real Time" airs only once a week, and Maher's vacation schedule would make almost anyone jealous. Maher's best bit: "New Rules," a biting essay that closes each show.
