Any Indian would know...

[Trojan]

An Indian tracker is taking some pioneers through the plains in the mid-1800's. Suddenly he stops and points. "Bear have babies." He says.

One of the younger pioneers runs up and asks, "How'd you know that!?."

"I know these things," replied the Indian.

They continue their journey, and a little while later the Indian stops, points, and says, "deer tracks."

"How'd you know that!?" asks the young pioneer once again.

"I know these things."

After another hour of journeying, the Indian jumps of his horse and puts his ear to the ground. "Buffalo come."

"How'd you know that!?"

"Ear wet."
