Did ya hear the one about the rancher?

He's watching his flock when this limousine pulls up. Guy in an expensive suit gets out and says "If I can guess how many cows you have, will you give me one?" and the rancher says "ok".

Guy gets on his cell phone, makes a call, waits a few minutes, and says "183". Rancher says "that's right" and the guy grabs an animal and starts to get into the car. Rancher says "hold on. I want a chance to win him back. If I can tell you what you do for a living, will you give him back?" and the guy says ok.

Rancher immediately says "You are a politician." Guy is dumbfounded but says "that's right, how did you know?"

"It was simple. You came out here where you weren't invited. You charged me for telling me something I already knew, and you obviously don't know anything about ranching."

"Now gimme back my dog."
