Two gorgeous blonde biologists were in the field one fine summer day. While following a game trail, they came across a pair of tracks. "Look! a pair of tracks" The first blonde said while pointing to the ground.
"Those are deer tracks," the other blonde replied.
"Oh no,"she said to the first, "Those are definitely moose tracks."
With this, they began to argue. In fact, they were still arguing when the train hit them.
