Episode: Season 4, Episode 6: St. Louis to Dogon Country
Ted appears in this episode, which aired in the UK on February 9, 1999. It’s described at IMDB: “Danny Glover and his wife Asake Bomani travel from St. Louis in Senegal to the Dogon Country in Mali.”
Unfortunately it does not appear to have been issued yet on disk, or digitally. It was available on YouTube for a while, and is still linked there, but has been removed. I’m including the link here in case it goes back up!
