An old cowboy enters a bar and orders a whisky. He sits down and sips at his drink. Soon after a young woman comes in and takes place at the stool next to him. She looks at him for a while and then she asks: "Are you a true cowboy?"
"Well," he answers, "I've spent all my life at a ranch and half of it on the backs of horses. I've repaired fences, I've herd animals and I've marked cows with the branding iron, thus I'm no doubt a cowboy."
She says: "And myself, I'm a lesbian. I think the entire day of nothing else but of women. When I wake up in the morning I think of women. All, what I do, if I shower or watch TV makes me thinking of women."
A bit later an old couple comes in and sits down next to the old cowboy and asks: "Are you a true cowboy?"
"Well," he answers, "I've always been thinking I were one, but I just found out, that I'm a lesbian."
