TOO FUNNY!
My favorite female Comediene is Etta May.
She's described as: A career school bus driver for ten years, Etta May learned how to handle unruly children by armor-ailing the seats, then braking and watching ?em roll. ...
Who does that sound like?
Here are a few short clips of her... the first one is her bit on being a school bus driver...
