Back in the 1980s, Gary David Goldberg's production company, Ubu, would follow popular TV shows (such as "Famiy Ties") with a photo of his black Labrador, holding a frisbee. A voiceover said "Sit, Ubu, Sit!" followed by "Good dog!" and a *woof*. It's become embedded in many people's memory and often referenced in pop culture.
To recreate it, just use this Skill. Say "Alexa, open Sit Ubu Sit!" and Alexa will take you down memory lane.
