13. Traci Bingham
Worst Performances: Baywatch (TV series, 1996-1998)
The probability that Traci Bingham never even had to audition for Baywatch is high. David Hasselhoff and his fellow show producers likely spent a few meetings chatting about bringing some diversity to the fake-breast-covered beaches, and, one day, Ms. Bingham strolled into their offices, took off her coat, and won the job without even touching a script.
With that scenario, we're actually giving the Hoff the benefit of the doubt. If he did actually see Bingham's acting know-how before casting her as the luscious Jordan Tate, dude's an even worse judge of talent than he is a pop singer.
