<P> Other memorable Flaherty characterizations included emotional talk show host Sammy Maudlin, seedy saxophonist - private eye Vic Arpeggio, aggressive elocution lecturer Norman Gorman, myopic public television host Hugh Betcha, and "crazy as a snake" ex-convict Rocco . </P> <P> SCTV ceased production in 1984 . </P> <P> Flaherty has appeared in a number of cult favorites, for example, playing the part of the Western Union postal worker who delivers Doc Brown's 70 - year - old letter to Marty McFly in Back to the Future Part II (1989), as well as the crazed fan yelling "jackass!" in Happy Gilmore . In season eight of Family Guy, Joe once again played the Western Union man in "Something, Something, Something, Dark Side". He likewise satirizes his Back to the Future Part II character in "The Big Bang Theory", this time playing a Vatican worker whose role is essentially identical to that of his Western Union character . </P> <P> In 1989, Flaherty played a guest role in Married...with Children in season - four episode "Tooth or Consequences", as a recently divorced dentist who must repair Al Bundy's teeth . </P>
