They just finished the TV-land version and I noticed something: There is a scene in which Fonzie and Pinky ride into the sunset that I have never seen since I first saw that on ABC. Why can't the networks arrange the episodes so they can show some of the deleted endings? The shows look like they are incomplete with the endings deleted.

Did you notice in that three part ep. the demolition is teams of two cars:
Fonzie & Pinky
The Malachi Brothers
But at the start of the demoliton, there is an odd number of cars.
