'St. Elsewhere' Reunion: Howie Mandel Was The Prankster Of The Cast (VIDEO)

Long before "Grey's Anatomy" and "House" ruled the airwaves, another medical soap was one of primetime's heaviest hitters: "St. Elsewhere," which ran on NBC from 1982-88. The show boasted many now-famous faces who got their big break in the halls of St. Eligius, including Helen Hunt, Mark Harmon, Howie Mandel, Ed Begley, Jr. and Denzel Washington.

"Good Morning America" (Weekdays, 7 a.m. ET on ABC) caught up with the cast 30 years after the successful drama came to a controversial close, sharing some insider info on what it was like to work on one of the most beloved series of all time (it was nominated for 63 Emmys -- winning 13 -- during its run).

One tidbit we gleaned from the GMA segment? That one of the show's most successful alums was quite the prankster on set ... Apparently, Howie Mandel loved to play tricks on his fellow cast-members; on one occasion a fellow actor went on vacation, so Mandel listed his house for sale. We wonder if he's tried to do anything similar to the crew on "Deal or No Deal?"
