Shank Fairy

When a stabbing occurred, and everyone who was around when the stabbing occurred, says they did not see anything because they were asleep or they were in the bathroom with all 30 other people who were around when the stabbing occurred. So, the Shank Fairy is obviously the one who did the stabbing.....

Jacob: Hey, Frank, who stabbed up this guy?

Frank: I don't know, everybody says they were in the bathroom when it happened. Nobody saw anything....

Jacob: That f'n shank fairy!!
