Kenner T-zzzers (1981 ad)

And another one from Johnny N's playlist Boy overalls. Original upload from The Museum of Classic Chicago Television.

Black boy wearing glasses kneeing in bibs. As usual brief scene. 

Compared to others rating 2-3.

Thanks for another suggestions. Neighbours and Home and Away, I already have, both rating 5. The Aurora Encounter, I have to check.
