This dates back to the rare '$10,000 Pyramid' episode (with guests JoAnne Worley and Richard Deacon) from 1973, which was incidentally posted somewhere on YouTube. Richard was giving the clues and had gotten the contestant up to the last $200 subject, 'Things You Unwrap'. The contestant said 'Things You Wrap' and was originally credited with the $10,000 win. However, the judge (possibly Bob Stewart, himself) was raising a 'red flag' to Dick Clark. They went to commercial, with Richard and the contestant seated in the WC. The contestant could be heard talking to Richard Deacon, asking if he should turn around, and was advised not to. When they started tape up again, Dick explained that due to confusion with the subject, the best thing to do was to replace the subject, put 12 seconds back on the clock, and play with a new $200 subject. The new subject was 'Things at a Party'. The contestant guessed the subject, won $10,000 legitimately, and everyone was happy.
