Three men are stuck on an island, their food supplies are beginning to run out so the first guy went out to get more stuff to eat.

The next day he came back with a deer, the second guy asked, "How did you get that?!"

The first guy said, "I found the tracks, I followed the tracks, and I found the deer."

The next day the second guy went out and came back with a bear. The third guy asked, "How did you get that?!"

The second guy, "I found the tracks, I followed the tracks, and I found the bear."

The next day the third guy went out and came back all cut and bruised. The first guy asked, "What happened?"

The third guy. "I found the tracks, I followed the tracks, and I got hit by a train."
