"It's time for an intermission
It's time for an intermission
It's time for an intermission
So grab yourself a snack
Yes, grab a tasty snack
Yes, grab a yummy snack
But we'll soon be showing more movies
We'll soon be showing more movies
We'll soon be showing more movies
So won't you hurry back?"
(sung to a jazzy version of "The bear Went Over The Mountain"...At least that's how I remember it.)

Anyway, this is how the movie theaters used to let the patrons know they were taking a break while reloading the projector with another feature. That way everybody got to stretch their legs and get something from the snack bar, like the usual popcorn and soda.
There was also a black-and-white version of this animation strip, which I'll be submitting after this one.
