- Retroactive Recognition:
- The 1989 series was the first to feature the "deliberate continuity errors" Observation round, and the sketches starred a young Steve Coogan, then most well-known as a standup comedian/impressionist and voice actor on Spitting Image, with the debut of his most famous comic creation, vain but inept and sociopathic broadcaster Alan Partridge, still two years away.
- In the 1989 series, one of the contestants in the first heat of Group B was Jim Shekhdar, who went on to become the first person to successfully complete a solo, unassisted, non-stop row across the Pacific Ocean between June 2000 and March 2001.note
- They Changed It, Now It Sucks!: Thrice. First messing with the formula and introducing a co-host with the 1995 series (basically trying to turn it into a clone of another ITV agility game, Gladiators), and later by the omission of the Response round in the 2009 revival. And then again by removing Intelligence in 2010.
