Kennedy memories: 25 for JFK

16. TV: Seinfeld (1992)

In a two-part episode featuring baseball star Keith Hernandez, this NBC comedy offered a parody of  “JFK,” complete with Zapruder-like footage. At one point, Jerry attempts a reenactment of Kramer and Newman being hit by spit after a Mets game, relying, as he says, on “the immutable laws of physics.” Ultimately, the secret spitter is revealed.
