Three blondes are walking through the forest when they come across a set of tracks.

The first blonde says, "Hey, look at that, deer tracks!"

The second blonde chimes in and responds, "No, Becky, those are moose tracks!"

The third blonde steps in and says, "You two are both wrong, those are obviously elk tracks!"

The three blondes kept arguing about what animal left the tracks until they were eventually hit by a train.
