End Credits: When no one is looking, the Crazy Dog makes his way out of the house utilizing the many secret doorways and goes in his doghouse. When he is inside, he sees his Mildred wig laying on the floor. He puts it on, and admires himself in the mirror looking at himself.
A running gag in this episode is that all the characters appearing in The Dog and Phony Show keep running in and out of trick doorways that lead to the most unexpected of places. Also, Rodney keeps hitting Murray thinking it's the Crazy Dog.
It's learned in this episode that the Crazy Dog that always chases Rodney and Andy around either is a girl or disguises himself as a girl dog named Mildred and can talk while being Mildred (wearing a blond wig.) The Crazy Dog also has a twin brother named Murray who is the opposite of the Crazy Dog and is completely nice.

Andy: Ewww! I sitting in a tub of vanilla ice cream!
Rodney: Here, let me help you out.
Andy: No, I'm fine.
