The Skipper, Alan Hale, Jr. Brings his one and only acting ability to The Andy Griffith Show. Years before Gilligan was taking it in the hammocks on the lost island, the Skipper took one last shot at a heterosexual lifestyle.
The Skipper visits Mayberry, where he sets his eyes on Thelma Lou, and chases her hard. Compared to Barney, the Skipper was a lot more man, and Thelma Lou was clearly giving the Skipper a window of opportunity.
Barney was a lot smarter than Gilligan, and he had the help of Andy too. So they figure out that if Thelma Lou makes the Skipper eat with a fork instead of his hands, that might sour him on women. After a lot of shenanigans about courtesy and manners, the trick works and the Skipper finally gives up on Thelma Lou.
Barney is overjoyed, but Gilligan would pay the price years later, when the Skipper made him his "little buddy." All the coconut oil in the world couldn't keep Gilligan from being sore.
