Lose horse joke

A cowboy walks in to a bar and says, "I want a beer."

So after he drank his beer he was about to leave then he noticed that his horse was gone.

He shouted, "If I don't get my horse back after this beer I am gonna have to do what I did in Georgia."

So he finished his beer and he saw his horse was back so he got on and rode a little, then the bartender asked out the window, "What did you have in Georgia?"

"I had to walk home."
