"Hey, if my friend comes by, tell him we're in the backroom?"
"Sure, what's he look like?"
"Well, he's tall, practically towers over everyone...brown hair, scar down his left cheek, carries a really big sword, wears a nosering..."
"Uh-huh."
"And has two horns sticking out of his head."
"Huh?"
"He's a Minotaur. Can't miss him."
