Let's All Go to the Lobby

An animated chorus line of treats (popcorn, drink, candy, etc.) dances down a theater aisle while singing a jingle that encourages the audience to visit the concession stand.

I can't count how many times I have seen this. While I never purposely sought it out, it has appeared in movies featuring theater scenes, and when I go to theater events it sometimes plays there, too. This has to be one of the bet-known advertisements, because anyone who has seen a fair amount of movies has to have run into this ad sooner or later.

Is it effective? I have no idea. It never made me buy soda or popcorn. But it's memorable, which makes it a strong little film, whether useful for selling things or not.
