They're black, they're brown,
They're up, they're down!
They're in, they're out,
They're all about!
They're far, they're near,
They're gone, they're here!
They're quick, they're slick,
They're insincere!
Beware! Beware!
Be a very wary bear!

...This is probably one of the most memorable Disney scenes I remember growing up, along with Pink Elephants on Parade... (Apparently I have a thing for hallucinated elephants because that's all that ever stuck with me.) I listened to the song again recently and then this out of control sketch happened. I may come back to it and finish.
