Track Examination Gone Wrong

A blond-haired girl, a brown-haired girl, and a ginger-haired girl were out walking when they came across some tracks.

The brown-haired girl looked at them and said, "I think they are elephant tracks."

Then the ginger-haired girl looked at the tracks and said, "No way, they are definitely duck tracks."

Finally, the blond-haired girl bent down to examine the tracks when she got hit by the train.
