While in England, Jethro falls for a young lady, but the Clampetts thinks a man wearing the kilt is the girl that Jethro has fallen for.
Jethro announces he's going to marry Col. Dunbarton's niece. Instead of seeing his niece (Sandra), Jed and Granny meet his nephew (Emlyn) instead, and because he's dressed in a Scottish kilt, they assume she's a homely woman, not realizing there really is a beautiful niece.—Dionysius Exiguus
