Setting for many a joke with a priest, a pastor and a rabbi

BAR

Think of a casual place where people from all walks of life might gather for a drink—and where punchlines often start with "so these three walk in...".

This clue plays on a classic joke setup where a priest, a pastor, and a rabbi walk into a bar—a well-known trope in comedy. The answer "BAR" isn’t just the physical place but the punchline’s expected location, making it a clever nod to the joke’s structure. It’s a cultural reference that relies on recognizing the familiar "walk into a bar" format.
