Movie: Airplane! (1980)

In the endlessly funny Airplane!, whenever the aircraft's co-pilot Roger Murdock (Kareem Abdul Jabbar) needs a break, it's time to bring in the auto pilot. Which, in true first-class comedy fashion, turns out to be an inflatable doll made up to look like a pilot, and named Otto.

And, unavoidably, Otto sometimes loses too much air and deflates. So, ever the team-playing trooper, stewardess Elaine Dickinson (Julie Hagerty) has to blow air back into Otto. Where exactly? Into the little tube that protrudes from his crotch area. Once he's back in action, fully inflated, Otto's face shows a grin beaming from fake ear to fake ear.
