Written by Richard Wade.
Starring Dudley Foster as Humphrey Hastings, Frances Bennett as Emily Hastings.

Almost every aspect of practical science over the last hundred years finds its way at one time or another into the Hastings household. The results are not always what we might expect - very rarely what the Hastings family expects. Only Humphrey himself remains unabashed by the events which take place in his ordinary-looking house in Twickenham.
