In "The Thin White Line", a flashback shows Peter Griffin as a security guard for George Harrison, watching Charles in Charge and singing along to its theme song while an intruder invades the home. On the evening of December 30, 1999, Michael Abram broke into the Harrison's Friar Park home in Henley-on-Thames and stabbed George multiple times, ultimately puncturing his lung. Harrison and his wife, Olivia, fought the intruder and detained him for the police. 35-year-old Abram, who believed he was possessed by Harrison and was on a "mission from God" to kill him, was later acquitted on grounds of insanity. Traumatized by the invasion and attack, Harrison rarely appeared in public afterwards.
