What's your favorite "walks into a bar" joke?

I like this one the best:

An old cowboy was sitting at the bar in Montana having a whisky. He was the personification of the word cowboy. Chaps, vest, plaid shirt, levis, boots scuffed and dirty, cowboy hat, etc. A young woman comes in and sits down beside him. She orders a drink and looks over at the old cowboy and says “you look like a cowboy.” He replies “yep, I’ve been a cowboy all my life. I ride herd on cattle, I brand cattle, I’ve worked with cattle all my life. I’m a cowboy. And you?” She replies, “I’m a lesbian, been one all my life, I think of women from morning to night, think of them naked, holding them, loving them, touching them, loving them, I’m a lesbian.” She finishes her drink and leaves. The old cowboy sits there drinking his whisky and a young man from the city walks in and sits beside him and orders a drink. He looks over at the old cowboy and says, “You look like a cowboy” The old cowboy answers back “ I always thought I was a cowboy, but now I think I might be a lesbian.”
