In its 26th season, this enduring variety show has a comedic field day parodying the 2000 presidential campaigns of George W. Bush and Al Gore -- not to mention the election itself and its controversial aftermath. Also this year, head writer Tina Fey gets in front of the camera and joins Jimmy Fallon at the "Weekend Update" desk, while guest hosts include Rob Lowe, Pierce Brosnan, Katie Holmes and Charlize Theron.
