"I am a lesbian" joke

An old cowboy dressed to kill with cowboy shirt, hat,
jeans, spurs and chaps went to a bar and ordered a drink.
As he sat there sipping his whiskey, a young lady sat down
next to him.
After she ordered her drink she turned to the cowboy and
asked, "Are you a real cowboy?"
"Well, I have spent my whole life on the ranch herding
cows, breaking horses, mending fences... I guess I am,"
replied the cowboy.
After a short while he asked her what she was.
"I've never been on a ranch so I know I'm not a cowboy,"
said the young woman, "but I am a lesbian. I spend my whole
day thinking about women. As soon as I get up in the
morning I think of women. When I eat, shower, watch TV,
everything seems to make me think of women."
A short while later she left and the cowboy ordered another
drink. A couple sat down next to him and asked, "Are you a
real cowboy?"
"I always thought I was, but I just found out that I'm a
lesbian."
