I remember 3-2-1 Contact and its show-within-a-show, The Bloodhound Gang. It had two main characters - a Black teen girl and a Black teen boy - and a younger White kid that, I think, was a different one in most every episode.
The teen girl would always answer the phone with the line "Bloodhound Detective Agency. Whenever there's trouble, we're there on the double. Mr. Bloodhound isn't here." After that, I always said to myself "...and never will be.", because no one on the team ever saw Mr. Bloodhound or heard his voice, unlike Charles ("Charlie") Townsend in Charlie's Angels where, even if the Angels never saw Charlie, they did hear his voice.
