A brunette, a redhead, and a blonde decide to go camping. 

They are in the woods and start to get hungry. The brunette follows bear tracks she sees, and hopes to bring back food.

She came back a little while later and had a bear.

The redhead sees some deer tracks. She follows the deer tracks on search for food. She comes back with a deer.

Finally, the blonde says, "I am going to follow tracks and bring back some food."

A little while later, the blonde comes back with blood all over her a broken bones.

The blonde followed the train tracks.
