A man wearing a ten-gallon hat and leather boots goes into a bar and sits down next to a woman. "Are you a real cowboy?", she asks him.
He responds: "For all my life, I have been tamed and ridden horses. I have repaired fences, herded and tended to cows and caught escaped cows. I think it would make sense to call myself a cowboy."
To which she says: "Interesting. I myself am a lesbian. I wake up thinking about women, when I am in the shower I think about women, at night laying in bed I think about women. I constantly think about women." They talk for a while, until she gets up and leaves.
An older couple enters the bar and sits down next to the cowboy. They eyeball him a short while and then muster up the courage to ask him:"Are you a real cowboy?",
to which he replies:"For all my life I thought I was a cowboy, but today I learned that I am in fact a lesbian."
