Rudy Giuliani - Seinfeld

In 1993, former New York City Mayor Rudy Giuliani joined the cast of ‘Seinfeld,’ playing himself in the seventh episode of Season 5, ‘The Non-Fat Yogurt,’ which is a fictional depiction of the 1993 mayoral elections.

In the episode, Elaine (Julia Louis-Dreyfus) dates a guy named Lloyd (Peter Keleghan), who works for NY Mayor David Dinkins when the latter is running for re-election against Giuliani. Rudy’s scenes were filmed one day before his real-life election took place.
