It's our first Encyclopedia Britannica short! Much like Coronet (and ACI, which we haven't been introduced to yet), a decent amount of the RiffTrax Shorts catalog is composed of Encyclopedia Britannica shorts.
Skipper Learns a Lesson is about a dog who has to learn to like other dogs based on what is inside them. No, I don't mean worms. I mean the fact that who a person is on the inside is more important than how they look.
Skipper learns this lesson by first rejecting the other dogs in the new neighborhood his family just moved to, somehow getting covered in poster paint, and then having the dogs reject him. Poignant stuff.
