In the classic stories of Dr. Doolittle, the doctor travels to Africa where he encounters the rare two-headed llama called the pushmi-pullyu. In a discarded chapter, the doctor narrowly escapes an encounter with a rhino-like animal called the stompmi-goreu.
Puts me in mind of an old joke about the meanest critter in the world, with a head on either end. “How does he s***?” “THAT’S why he’s the meanest critter in the world!”
“I’m not talking to you.”
