15. BIG BROTHER (CBS, 2000-present)
The contestants may be lewd, crude, and often reprehensible (your legacy is secure, Evel Dick), but BB is a voyeuristic hoot because it so delightfully embraces its cheesiness. You know a show can laugh at itself when even the host, Julie Chen (above), revels in her not-so-flattering nickname, the Chenbot.
Best season: 2 The egomaniacal Will ”Dr. Evil” Kirby wins — after repeatedly warning everyone that he is a lying bastard.
