'Psych's' Martin Sheen 'cameo' was one of Dule Hill's season highlights

dule-hill-martin-sheen-psych-USA.jpg "West Wing" fans got a treat during "Psych's" penultimate episode, "A Nightmare on State Street," when Gus (Dulé Hill ) found himself in a series of nightmares and in one, actor Martin Sheen made a "cameo" as Gus' dad, in photo form.

Sheen and Hill starred for seven seasons on "The West Wing," with Sheen playing Hill's de facto father figure, so it was a fun joke for fans. Hill tells Zap2it that over the eight years of "Psych," he always wanted his former co-star to appear on their show but they could never make it work.

"I wanted to actually get Martin Sheen's physical form in the show, but the fact that we can get a picture of Martin Sheen and me calling him papa was one of the highlights of the season," says Hill. "Throughout the years we tried to get him on and the schedule could never really work it out."

"Psych" bows next Wednesday, March 26 with its series finale on USA.
