It seems nobody remembers the original beginning of the show which started with:
"Don't touch that dial, don't touch that other dial, and stop touching yourself! SCTV is now on the air."
Obviously it was cut for later airings and has practically been forgotten, but it was part of the first season when the show originally aired.
It also seemed to me that the best season. The show also tended to parody CityTV and their shows a lot.
