Suave and fastidious British archeology professor "Patterson" (Terry-Thomas) is forever fending off the attentions of his amorous female students, so hopes that the announcement of his engagement to "Helen" (Celeste Holm) might calm things down. He's in for quite a shock though when her daughter "Libby" (Tuesday Weld) shows up having absconded from boarding school. Now he knew nothing of her, nor she him so when she catches him in the shower - well that's just the start of the misunderstandings galore that follow. None of this is helped by his youthful neighbour "Mike" (Richard Beymer) who quickly takes a bit of a shine to her. Poor old "Patterson" is quickly out of his depth as the scenarios become sillier and the intervention of a certain four-legged "Jessica" adds even more mayhem as she fancies a gnaw on his recently arrived ancient dinosaur bone. It starts off quite engagingly but does rather fall into a repetitious frying pan to fire series of predictable scenarios that even the naturally talented Terry-Thomas struggles to rejuvenate after half an hour of romantic, under the bed, semi-slapstick. Beymer and Weld look like they are enjoying themselves though, and the few scenes with Holm make it a watchable enough comedy that epitomises the spirit of the British stiff upper lip contrasted with a good dose of American free love and even a bit of French joie de vivre too! You'll never remember it, but it passes ninety minutes effortlessly.
