Check this out. Recently, I was working on a spot with Jetsons characters in it, and so on my quest for reference, I came upon this scene from the show where Astro did his signature full-face lick on George -- he did this quite often, so when I was watching this initially it didn't seem like a big deal. But then I frame-by-framed it, and I was amazed by how much those guys stretched and pulled the main characters!
I love animating on scenes like this, where you can contort the characters like they're taffy. You'll be amazed to know how many times I've been told to tone down a pose because it was not "on-model." Phooey. I guarantee you that this scene would've been asked to be re-done if it was produced nowadays. "Yeah, I dunno. It just doesn't look like George..."
