Three cowboys are sitting around a campfire, out on the lonesome prairie, each with the bravado for which cowboys are famous. A night of tall tale telling begins. The first says, "I must be the meanest, toughest cowboy there is. Why, just the other day, a bull got loose in the corral and gored six men before I wrestled it to the ground by the horns, using my bare hands."
The second can't stand to be outdone. "Why that's nothing. I was walking down the trail yesterday and a fifteen foot rattler slid out from under a rock and made a move for me. I grabbed that snake with my bare hands, bit its head off, and sucked the poison down in one gulp. And I'm still here today."
The third cowboy stayed silent, ...slowly stirring the coals with his penis.
