My guide made a dismissive noise. "After, before. . . these things all go back. They talk about the labyrinth of Minos, but that was nothing by comparison to this. Just some tunnels with a horn-headed fellow wandering lonely and scared and hungry. He wasn't really a bull head. You know that?"--From a story in Neil Gaiman's Trigger Warnings, an ok collection with three or four good, creepy stories.
"How do you know?"
"Teeth. Bulls and cows are ruminants. They don't eat flesh. The minotaur did."
"Hadn't thought of that."
