Perfect Bid: The Contestant Who Knew Too Much is a 2017 American documentary film that profiles Ted Slauson, a super fan of The Price Is Right. Interviews with Slauson reveal how he became fascinated with the show in the early 1970s, which drove him to memorize the prices of products, and his involvement with contestant Terry Kniess, who bid perfectly on a showcase in 2008.
