Real citation: "The Kinder Billy is a scruffy looking beast. I call him a 'Neandergoat' because he looks like a goat version of a caveman. He's real friendly, which is ok - until they are in "rut". It's NOT a good idea then."

Made-up citation: "To make Oprah's special Satanic brownies, the eye boogers of a neandergoat must be dissolved in the blood of a virgin, the ear wax of a meercat, and a shitload of chocolate."
