I.R Baboon got no pants.
I.R Baboon got nothing to hide.
It has been decades since I watched the cartoon in earnest. I have forgotten most of the lore. One thing I do remember is thinking the baboon is a girl and the weasel is a boy. So I am surprised to read the Wikipedia page that says I.R is male.
I am happy to agree I.M Weasel is meant to be a man. He is altogether a more civilised and more human character, who speaks perfect Oxford English in the sonorous tones of Michael Dorn. K'plah!
But the Baboon has a crude cartoon voice. Speaks broken English, in what I imagine a real baboon would sound like if it learnt to speak. And we all know boy baboons look the same as girl baboons.
Is there any canon reason to believe I.R is a pretty lady baboon and not a smelly-yucky boy baboon?
