One of the niftiest things about Kenner’s KITT toy from the early ’80s was that there was a small dial underneath the car that allowed you change the speed of the voice; this was intended to counteract the tendency of the voice to go too fast when the batteries were new, and slow down when the batteries were dying. A nifty feature–which apparently everyone forgot about during the making of this ad. Those are clearly new batteries in KITT–it sounds like Mr. Feeny doing an Alvin & the Chipmunks impression.
The girl on the bottom right at the end of the Care Bear Cousins ad just doesn’t seem that into it.
