At first the Sycamores seem mad, but it is not long before we realize that if they are mad, the rest of the world is madder. In contrast to this delightfully eccentric family are the straight-laced Kirbys. When Tony Kirby falls in love with Alice Sycamore and brings his parents to dinner on the wrong night, chaos ensues! Will Alice break off their engagement? Will Tony’s parents survive the evening’s revelations? Will Grandpa pay his taxes? Will Mr. DePinna take his clothes off? Will the pyrotechnics in the basement end it all? Get the answers to these and many more questions in this rollicking comedy!
