Remember this character that appeared along with the Saturday morning cartoons on ABC? I do as I watched cartoons faithfully every week.
According to Toontracker, "The character Timer (voiced by Len Maxwell) originally appeared in "The Incredible, Indelible, Magical, Physical Mystery Trip", an ABC Afterschool Special that combined live-action with animation. This 1973 DePatie-Freleng Production, in association with Sienna Productions, was an educational and entertaining journey which took two youngsters, Joey (played by Michael Link; animated version voiced by Peter Broderick) and Missy (played by Kim Richards; animated version voiced by Kathy Buck), through the mistreated body of their Uncle Carl (played by Hal Smith), who has lived a hard life, failing to maintain his health. The kids are miniaturized prior to the trip by Timer. The special was later re-broadcast as a two-part ABC Weekend Special."
Here is one of my favorite clips:
