The concussion
Slipping around and bumping your head is never funny. Well, it’s usually not funny, especially when the person suffers from a concussion. This story is told from the perspective of a restaurant cashier. He noticed that one of the servers was having a difficult time balancing a tray of food when the expected occurred in front of him.
An oil slick caused the server to throw his legs above his head. The platter he was holding came cascading down on top of him in front of all the dinner guests. The poor dude bumped his head pretty hard, and the restaurant was silent for a few moments.
