Grandad - Season 2 (1980)

Grandad is suffering from insomnia, so stage act The Great Mesmo hypnotises him to fall asleep whenever he hears the sound of a bell. Unfortunately for Grandad, Mesmo forgets to cancel his hypnotic command the following day.

Mr. Watkins decides to take a secret holiday to avoid any more stress after arguing with Grandad. But when the short-sighted Jill visits from the council, she sees Grandad jokingly strangling a dummy - and thinks he's committing murder.

Mr. Watkins finds that there's a £57 discrepancy on the year's accounts, so gives Grandad an ultimatum - either he sorts out the accounts or he will be fired. Grandad plans a way to get out of trouble by pretending he's lost his memory.
