This week’s DILF was an easy choice, a real no brainer.  I was watching one of my favorite shows this season, Ringer and found myself glued to the screen watching  guest star Gregory Harrison.During his days of prominence in the ’80s, handsome, powerfully built American actor Gregory Harrison became the unofficial poster boy of the Catalina Island chamber of commerce. As a native of that offshore isle, Harrison frequently guested on talk and variety shows, elucidating the natural wonders of both Catalina and the Avalon resort. A graduate of New York’s Actors Studio, Harrison briefly supported himself as a nightclub doorman before securing small film and TV roles. Harrison’s most memorable credits were for the small screen: He played Logan 5 on Logan’s Run (1977), Michael Sharpe on the final 1989-90 season of Falcon Crest, and the title role in the brief 1990 sitcom The Family Man. Harrison’s longest TV-series run was seven seasons (1979-86) as “Gonzo” Gates, the Vietnam-vet doctor on Trapper John MD (1979-86).
