Bob Barker, seen here in 1997, has hosted "The Price Is Right," the longest-running game show in history, since September 1972.

The "Guinness Book of World Records" named the 80-year-old star television's "Most Durable Performer." Barker has given 3,524 consecutive performances since his TV debut, "Truth or Consequences." But the title also suits him because he's been sued by nine ex-employees and never lost.
