Bar visit

Alright listen up, smarty pants! You see, skeletons don't have any muscles or ligaments. So when they walk into a "bar" – get it? Not the drinking kind but a metal rod – they just collapse because they can't hold themselves up. It's funny because it plays on the double meaning of "bar" and the physical limitations of being a skeleton. You probably have strong bones but you sure ain't got a strong brain.
