That's a big ...

I remember seeing an Animation Fesitval in the early 90's that had a short film with a gag similar to this in it. I can't for the life of me remember the name of the animated short. If it comes to me, I'll be sure to put the appropriate credit for the inspiration here! (But that's a big IF!)
