No. Jerry Seinfeld was not in 'Pulp Fiction'. 'Pulp Fiction' is a Quentin Tarantino movie known for its edgy and non - linear storytelling, with a cast including the likes of John Travolta, Uma Thurman, etc. Jerry Seinfeld's work is in the realm of stand - up comedy and his sitcom, which has no connection to the world of 'Pulp Fiction'.
I think Jerry Seinfeld is considered a relatively clean comic. His humor often relies on witty observations and situational comedy rather than anything overly risqu茅 or vulgar.
I'm not sure if there is an exact Jerry Seinfeld look alike in Pulp Fiction. I don't recall any character that has a very distinct resemblance to Jerry Seinfeld. But it's possible that someone might think a certain character has some similarities in appearance or mannerisms in a very loose sense.
