What's your favorite classic cartoon noise effect?

Anyone who doesn’t vote for the Goofy fall sound hasn’t watched enough cartoons. A true classic sound. Only thing comparable is the falling whistle & pow of Wile E. Coyote falling into a canyon. Yes…I’m gatekeeping cartoon sound effects.

Don’t forget the according sound his body makes as he’s walking away from landing and getting crushed.
