A clear sign that the episodes were shown out of recording sequence occurs at the start of the episode when Terry talks about Sandra Dickinson having been on the series before, despite this being her first televised appearance. Although not factually incorrect from Terry's perspective (Episode #2.13 (1979) having being presumably recorded first) the scheduling does make his comment nonsensical.
During the first "Supermatch Game", Terry says "chooser", instead of choice, before correcting himself.
When Terry first speaks to Bobby Knutt, he moves his microphone away from his mouth, causing his voice to dip.
