1940 - Goofy's Glider

"Also, it should be noted that this cartoon was made before and actually came out before "How to ride a Horse" (the Goofy "how-to" short included in the feature, "The Reluctant Dragon"). "Horse" is generally cited as the very first "how-to" short in the nature of this kind (Goofy demonstrates "how to" do something, with off screen narration, but ends up doing it all wrong instead) but this one is, in reality, the first of those cartoons in the series."

On a side note: RUclips revealed that I made enough viewers with this to be able to make money with ads. I hope the god of copyright law (i know you're up there!) will smite anyone making money off someone else his work.
