Delivering the usual merriment and timeless humor that kept its audience laughing for nine years, the hit sitcom says farewell. Naturally, the whole screwball Barone clan -- portrayed by stars Ray Romano and Patricia Heaton, along with supporting players Brad Garrett, Peter Boyle, Doris Roberts, Madylin Sweeten and Monica Horan -- is on hand for the series windup. Included is the show's pilot episode (televised Sept. 16, 1996).
