The Chuck Wagon was a reference to a series of commercials run in the 1970s for Purina's Chuck Wagon dog food.
In the commercials, a tiny covered wagon would appear from somewhere, often a bag of dog food, and race across the floor as the family dog chased after it, before slipping away.
The dog was the only one that was able to see this going on.
