S5·E27 The Doctors

Granny mixes up a batch of her 'spring tonic' & takes it to the bank. Jed swaps it for root beer. Dr Clyburn wants to charge Granny with dispensing without a licence. Mr Drysdale begs him not to & asks him to invite Granny to his surgery to see how modern medicine is performed. Against his better Judgement he agrees & invites Granny to his office. Granny thinks it's a date & Dr. Clyburn is interested in her. It's his day off but he's showing her all the modern devices, Granny wonders why he has no patients. Later Granny goes on TV advertising his services to get him some patients.
