Goofy's Glider.

Yet another sport is made 'easy' for us by Goofy's demonstration how- never, ever, to try anything for real, least of all with a glider-flying machine he launches in ways that would kill anything but a cartoon character, such as a giant catapult and even a canon. Meanwhile Goofy proves totally incapable to control any of its movements in the air, let alone the 'landing' which is too messy even for a bombshell.
