Granny's Spring Tonic - S1.E27

Miss Hathaway's brilliant-but-frumpy bank protegee Gloria (Lola Albright) is really a sultry gold-digger with eyes for Jed's $34 million, and Jed's just had his annual dose of Granny's spring tonic. Pearl and Granny are a little suspicious of her. Gloria claims that she has to marry a mountain man. Seeing through her scheme, Jed says that's a good idea, but she'll have to wait 3 or 4 years until Jethro is old enough.
