I assume you're already humming the song, if you're either old enough to have gone to the old movie palaces in their heyday, or caught the legendary footage produced by Chicago's Filmack being used ironically in some way more recently.
Anyway, I found a link to the YouTube version of this unforgettable bit of film history (now on the National Film Registry!) on a silent movie buff's blog, which goes on to reveal even more culinary wonders of the moviegoing past such as... chili in a cone.
Yikes.
Let's All Go To The Lobby!
