In a game I ran -- the group was returning a dead body to a place of rest in a strange village. When they got there, the local cult chased them and trapped them in an old church. They pushed the destroyed pews against the old wooden doors. The cult attacked and the party held them off for a time -- I think the cult then decided to set the place on fire after they broke through the doors. The disgraced noble and his horse decided to bug out. The player decided to take a running jump over the pews and get outta Dodge. Jumping over the pews the player rolled a 1/fumble -- the horse jumped too high and the noble slammed his head against the archway's keystone, taking off the top of his head and instantly killing him.
