Happy hideaway! 2 BR, 1 BTH beach house PRICE $679,000. Happy Days fans, take note: If you've ever wanted Mrs. Cunningham as your next-door neighbor, here's your chance. Marion Ross -- who starred as the doting '50s mom on the long-running series -- is putting one of her Cardiff-by-the-Sea, Calif., cottages on sale (she's hanging on to the one next door). The cozy, 1,200-square-foot abode features a fireplace, hardwood floors, a deck, and a patio. No word on whether the Fonz has dibs on the garage.
