An old cowboy went to San Fran for a visit, he walked into a bar and ordered a drink. As he sat sipping his whiskey, a young lady sat down next to him. She turned to the cowboy and asked, "Are you a real cowboy?"
He replied, "Well, I've spent my whole life on the ranch, herding horses, mending fences, and branding cattle, so I guess I am."
She said, "I'm a lesbian. I spend my whole day thinking about pussy. As soon as I get up in the morning, I think about pussy. When I shower, I think about pussy. As I watch TV, or even eat, I think about pussy. Everything seems to make me think about pussy."
The two sat sipping in silence. A short time later, a man sat down on the other side of the old cowboy and asked, "Are you a real cowboy?"
He replied, "I always thought I was, but I just found out I'm a lesbian."
