Given the that name of the comic is in reference to this fable, I thought it would be an appropriate first comic. The story, according to my book of Aesop's fables, reads as follows:
A wolf resolved to disguise himself in order that he might prey upon a flock of sheep without fear of detection. So he clothed himself in a sheepskin, and slipped among the sheep when they were out at pasture. He completely deceived the shepherd, and when the flock was penned for the night he was shut in with the rest. But that very night as it happened, the shepherd, requiring a supply of mutton for the table, laid hands on the wolf in mistake for a sheep, and killed him with his knife on the spot.
When I was making this comic, I read the Wikipedia article about the story, and interestingly, Aesop isn't actually the author. The idiom itself first arose in the New Testament, and the first fable with these specific events came from a 12th century Greek author. As I was reading more about the history and variants of the story, I got several other ideas, so I might make another version of this some day.
