Here in "Gabby Goes Fishing", Gabby comes upon a kid fishing. Although the kid is doing extremely well on his own, Gabby insists the kid watch him do it better--at which point, Gabby completely screws up--losing the fish the kid caught as well as his bait. Then, he uses a boat and makes things even worse.
Gabby was a character developed for the Fleischer Brother's first full-length film, "Gulliver's Travels". Someone must have thought it was a good idea to spin this character off to a string of shorts--though after seeing several, I don't think this was a great idea. This is because in each, Gabby plays a super-obnoxious know-it-all--a guy who invariable messes up things around him because he insists he is an expert at everything--even things he's never attempted. A little of this goes a long way--and by the time I'd seen just a few of these films, I really came to hate Gabby even though the animation quality was very, very nice.
