Mr. and Mrs. ???

After hearing a report through the radio that the judge who married the Howell's wasn't authorized, the castaways decide to have a second wedding for the Howells, with the Skipper presiding. Because a marriage by a sea captain isn't legal on land, the marriage takes place on a raft in the lagoon. But during the ceremony the Howells (although it seems Mrs. Howell is Ms. Wentworth again) call off the wedding, after some bickering. The castaways cook up a plan to make the Howells jealous of each other. When that scheme fails, the Skipper dresses up like a headhunter, which ends in Mr. Howell protecting Ms. Wentworth, throwing a coconut at the Skipper's head. The Howells are back together! The next day, however, a retraction comes over the radio saying that it was a different judge that was a fraud, not the one that married the Howells. So the Howells were married all along!
