Q: Question: How old was the series that Grampa and Jasper imitate? Passage 1:Born in Bucharest, her parents were the writer Vasile Demetrius and his wife Antigona (nee Rabinovici). Her beloved father had attended Saint Sava High School, where one of his classmates was Ion G. Duca, who would become Lucia's godfather. Her mother was a baptized Jew; she had numerous siblings and the family was very poor. She attended the elite Maria Brancoveanu central school from 1921 to 1928; its director, to whom she grew close, was the widow of Barbu Stefanescu Delavrancea. This was followed by the University of Bucharest, where she earned degrees in literature (1931) and philosophy (1932). A student at the Dramatic Arts Conservatory from 1928 to 1931, she had Ion Manolescu as a professor. She formed part of the Sburatorul literary circle. Asking Ion Marin Sadoveanu for help in finding a job, he sent her to act at Cernauti, and would also appear at Brasov and Bucharest, invariably in minor roles.
Passage 2:He had more likeable roles in two British children's TV series: The Ghosts of Motley Hall, which ran from 1976 to 1978 on ITV (produced by Granada Television), and as "Slugger" in Follyfoot, which ran from 1971 to 1973, also on ITV (produced by Yorkshire Television). He was in several other films and Everyday Maths (1978), a British TV schools programme starring Jack Wild as English's grandson. In 1978 he was the subject in This Is Your Life, while in May 1983 he was a guest on Desert Island Discs with Roy Plomley. Also in 1983 he played Frosch in Die Fliedermaus with English National Opera at the London Coliseum. In 1985 he appeared in an episode of the American TV series Magnum, P.I..
Passage 3:Additionally, Homer sings Billy Joel's 1983 song "Uptown Girl". After drinking the tainted juice, Grampa and Jasper sit on a bench, laughing like the title characters from the series Beavis and Butt-head, while Flanders hallucinates skeletons and dancing bears (images associated with the Grateful Dead), marching hammers (from Pink Floyd's 1982 film Pink FloydThe Wall) and The Rolling Stones' lips and tongue logo. Mr. Burns' film is credited as "An Alan Smithee Film", a reference to the Alan Smithee pseudonym credit used by directors who wanted to be disassociated from a film on which they had lost creative control, to the detriment of the final product. When Barney drinks alcohol to prevent the bad effects from the tainted juice, a pink elephant comes to his rescue, referencing the scene in Dumbo where Dumbo and Timothy drink alcohol and see pink elephants. Seth and Munchie's dog is named Ginsberg, thought to be a reference to beat poet Allen Ginsberg. Homer putting the flowers in the policemen's rifles is a reference to the iconic October 22, 1967 Life magazine picture, "Flower Power" by Bernie Boston.
