Simmy Bow (Man in Diner) After Pee-wee tells the diner full of patrons, "Large Marge sent me," this unnamed man in the diner explains to him that Large Marge had died a decade ago. Bow died in 1987 at 66 from complications from a stroke. His last film was Burton's Beetlejuice, in which he played a deceased janitor. (Via TMDB)
