A salesman is driving toward home in Northern Arizona, when he sees a Navajo man hitchhiking. Because the trip had been long and quiet, he stops the car and the Navajo man climbs in.
During their small talk, the Navajo man glances surreptitiously at a brown bag on the front seat between them.
"If you're wondering, what's in the bag," offers the salesman, "it's a bottle of wine. I got it for my wife."
The Navajo man is silent for awhile, nods several times and says: "Good trade."
At the restaurant
Waiter: "How did you find your steak, sir?"
Customer: "Well, I moved potato and there it was."
