Gabby was spun off from Max & Dave Fleischer's adaptation of Gulliver's Travels into a short-lived series of shorts for Paramount in the early 40's. To be honest with you, Gabby (Pinto Colvig) was one of the reasons I didn't like "Gulliver". Did we really need Jonathan Swift's novel to be adapted into a musical? Not really, but that's what the Fleischers decided to do. Paramount took a bath with "Gulliver", and eventually, the Fleischers left within a couple of years.
Away from Lilliput, Gabby's just another guy dealing with the usual tropes. In the case of "All's Well", from 1941, Gabby sees a crying baby, left all alone. Thinking the child needs his diaper changed, Gabby sets out to address the issue........
When the title song plays as an instrumental later in the film, it sounds like it was also used as the theme for Dennis The Menace more than a decade later. Of course, I may be wrong, but......!
