of the experiments has resulted in a complaint to OFCOM being upheld for fear that it would encourage children to imitate a dangerous procedure. The original Lab was a plain white room located somewhere in the large studio. Post revamp it occupied a fairly large part of the studio in an enclosed set. However, to make room for a new seated area within the enclosed set, and larger outdoor-oriented experiments, the Lab was reduced to at least half its original size and equipped with a cupboard that acted as a portal to the outdoors for larger experiments. When the programme was renamed Saturday Showdown, the show no longer had the Doc or his lab. Though on 18 March 2006, the Doc made a surprise appearance at the end of the main show. The part went as follows: Just as Holly and Stephen are about to say goodbye, Stephen found a German towel. They both say, "He isn't back, is he?" and we see through the door's frosted glass the blur of The Doctor as he shouts through the letterbox. But viewers without cable or satellite never got to see him that week, as he only fully appeared on the CITV Channel's Holly and Stephen's Saturday Showdown Extra. Though Stephen asked the Doc on the show if he could come back next week, it was to be a one-off appearance. However, the Doc re-appeared for the final show on 1 July 2006. Shows MoM was also host to many children's shows and cartoons, including SpongeBob SquarePants and Finders Keepers. After the launch of the CITV channel, viewers could switch over for a different show (similar to the interactive feature on CBBC's Mighty Truck of Stuff).
