It is an xray of the Australian Prince Rex, who just happens to be coming to visit David that day. David tells Susan about how he and Lisa went to Australia a long time ago. Rex was just a boy then, but he was a lot shorter than his twin brother. David found out Rex was allergic to his boomerang and told the prince to drink lots of fruit punch.
