Everyone starts the show with a stereotypical Native American "How" each episode.
"How" was originally broadcast live, and consequently most of the episodes were not retained in the archives; subsequent acquirers of the Southern Television archives - such as Meridian TV, Endemol and Southern Star - also appear to have junked a large number of the original 2" tapes in the 2000s, as the episodes were deemed of no commercial value. Out of 252 episodes (including the pilot), only 21 are known to exist as of 2020. This includes 7 episodes which exist only as domestic video recordings. The earliest believed to be retained hails from 15th January 1975.
