Meep Meep! The surprising history of classic cartoon sound effects

We all know what the scrambling cartoon caveman in The Flintstones sounds like, or the sound of a cartoon roadrunner sticking out his tongue. But these classic cartoon sounds don’t exist in real life. Where do they come from? How did somebody settle on a sound that’s so different from anything in the real world?

I love this video. These cartoon sound effects are as familiar to me as my own voice.
