A priest, a rabbi, and an atheist walk into a bar. The bartender points to a sign that says "NO JOKES SERVED HERE" and asks them to leave. They head out without a word.
The next day, a horse walks in. Same deal—bartender points to the sign, and with a long face, the horse leaves.
The following day, a chicken walks in. The bartender points to the sign again and says "Sorry, no jokes served here."
The chicken, annoyed, asks "Fine. So where can I get a drink?"
The bartender replies "Try the bar across the road."
