Rat-trap

Being at a loss for a coachman, Cinderella said, "I will go and see if there is not a rat in the rat-trap—we may make a coachman of him." "You are right," replied her godmother; "go and look."

Cinderella brought the rat-trap to her, and in it there were three huge rats. The fairy chose the one which had the largest beard, and, having touched him with her wand, he was turned into a fat coachman with the finest mustache and whiskers ever seen.

But above, perched each upon its own stone, tall, gray, and withered, more like dead and dried specimens than actual living creatures, sat the horrible males, absolutely motionless save for the rolling of their red eyes or an occasional snap of their rat-trap beaks as a dragon-fly went past them.

Everyone says he's got a rat trap mind.

He smiled, his wide rat-trap mouth splitting to show bad teeth.
