When three infants must depend on a goofy TV repairman turned baby-sitter, it s triple the hijinks, triple the fun and triple the laughs! Whether it s changing diapers, warming the bottles or singing off-key lullabies, this in-over-his-head nanny will have you up past your bedtime - because he s played by the incomparable Jerry Lewis. In Rock-A-Bye Baby, Lewis reaches new heights of buffoonery as the gawky Clayton Poole. When his childhood sweetheart, now a Hollywood actress (Marilyn Maxwell), finds herself widowed, pregnant and set to star in White Virgin of the Nile , she turns to Jerry to keep the kids happy, healthy and under wraps. With the King of Comedy in charge, the nursery will never be the same.
