One of them is extremely smart, one is average, and one is extremely stupid.
One day, it is the extremely smart one's turn to catch and cook dinner. He goes out and comes back with a bear.
The other two are astounded and ask, “How did you catch this bear?”
The extremely smart one replies, “I see tracks, I follow tracks
I see bear, I shoot bear.”
The next day, it is the average one's turn to hunt and cook dinner. He goes out and returns with a deer.
The extremely stupid one is amazed to see the catch and asks, “How did you catch this deer?”
The average one replies, “I see tracks, I follow tracks
I see deer, I shoot deer.”
The following day, the extremely stupid one goes out to hunt and comes back half dead.
The other two ask, “How did you mess up so badly? Didn't you follow our instructions?”
To which the stupid one replies, “I did! I see tracks, I follow tracks. I see train, I shoot train, then it hit me.
