Since Lenny Bruce and the JFK assassination were invoked, I will see the Kobe Bryant joke and raise it by Paul Krassner.

Krassner's most notorious satire was the article "The Parts That Were Left Out of the Kennedy Book", which followed the censorship of William Manchester's book on the Kennedy assassination, The Death of a President. At the climax of the grotesque-genre short-story, Lyndon B. Johnson is described as having sexually penetrated the bullet-hole wound in the throat of John F. Kennedy's corpse.[15] According to Elliot Feldman, "Some members of the mainstream press and other Washington political wonks, including Daniel Ellsberg of Pentagon Papers fame, actually believed this incident to be true."[16] In a 1995 interview for the magazine Adbusters, Krassner commented: "People across the country believed – if only for a moment – that an act of presidential necrophilia had taken place. It worked because Jackie Kennedy had created so much curiosity by censoring the book she authorized – William Manchester's The Death Of A President – because what I wrote was a metaphorical truth about LBJ's personality presented in a literary context, and because the imagery was so shocking, it broke through the notion that the war in Vietnam was being conducted by sane men."[17]
