Jim, the hand from Wyoming says, "I must be the strongest, meanest, toughest cowboy there is. Why, just the other day, a bull got loose in the corral. It had gored six men before I wrestled it to the ground by the horns with my bare hands and castrated that sucker with my teeth."

Mike, from Idaho, couldn't stand to be bested. "That's nothing, I was walking down the trail yesterday and a 15 foot diamondback rattler slid out from under a rock and made a move for me. I grabbed that bad-boy with my bare hands, bit off its head, and sucked the poison down in one gulp and didn't even get a belly ache."

Old Gila River John, the cowboy from West Texas, remained silent, slowly stirring the campfire coals with his pecker...
