There was once a dog who used to live at a train station. One day, the dog fell asleep by the railroad tracks and left his tail on one of the tracks. Of course, eventually a train rolled by and ran over the tip of his tail. The dog was surprised and awoken by this sudden jolt and turned around to see what happened to his poor tail. When he turned his head, it too, got caught under the train and killed him dead.

Moral of the story:

Don't lose your head over a lil piece of tail
