No Kidding (1960)

"From the producers of Carry On Nurse another daffodil to shake your funny bone!"

A young couple, David and Catherine Robinson, has to turn their large country house into a money-making proposition. Their solution is to invite the kids of the rich and famous to spend a summer enjoying all the loving care and attention they miss at home. After the youngsters arrive, David quickly realizes what the offensive little punks need is some real discipline, and so the summer begins.
