Some Mothers do ‘ave em’ (1978) Series Three Ep:4 Men as Women
Frank proves a destructive streak doesn't qualify for the demolition business, incurring a hearing impairment. Grandpa Spencer writes to announce his arrival in Britain. Dr. Mender is annoyed by Frank's frequent pointless visits, this time a present for him as his birthday is the same as Jessica's. Frank also sees him rehearse with another doctor for the hospital pantomime, but doesn't get it. A fake alert for Jessica brings each doctor in turn, pressed for time to change from the stage costumes.
