I was once playing pool with some friends, when one of them took his shot, staggered, and pitch backward, crying out..."Augh! I pulled my arse!"
We should have helped him. We should have gone over and dragged him to a chair, or couch or something.
That was not possible however. The other 3 people in the room had within seconds pitched to the ground themselves, unable to control our laughter, trying to get handholds on the pool table to pull ourselves up to an occasional cry of, "I'm not kidding! My arse! Augh!"
This continued for some time.
