You can never really know if the joke will work or not. But you can definitely understand when it's better not to joke at all.

"Let's make a show about nothing," George Costanza once suggested to Jerry on Seinfeld.

In truth, the actual show is considered to be about nothing. The creators made it clear that they didn't want to have a big main storyline that would grow over the course of the series.

In fact, their daily lives are the focus of the show, and any little thing can become the overall focus of an episode or even a season. But what made Seinfeld different from other sitcoms was the attention to detail.

The series ended 25 years ago, but it remains one of the most rewatchable and fan-favorite shows of all time. All thanks to the showrunners, of course, and the cast.

And by cast, we mean not only the main quartet, but also every minor character who appeared on the show and made random episodes just plain hits.

This also goes for one of the most unforgettable characters of the show, The Soup Nazi, brilliantly portrayed by Larry Thomas. He really managed to make the entire season 7 memorable with this episode.

The Soup Nazi is an episode about a very strict chef, Yev Kassem. He's known for running his own soup kitchen where the rules are exaggeratedly strict.

Although this may seem unnatural at first, even the slightest mistake by a customer can result in them not getting the food they paid for. Sometimes they even get banned (like Elaine, for example).

So in spite of all the attitude, the people in Seinfeld keep coming to that place because the soup is very tasty. They just follow the rules to get what they want.

As it turns out, Yev's character was based on a real-life chef who wasn't too happy about his portrayal on the show.

Ali Yeganeh is an Iranian soup vendor who ran Soup Kitchen International in New York.

And it's no surprise that he didn't like his character in the episode. People actually started comparing Ali to the character and it just made him angry to be called a Nazi.

Also, the episode's writer Spike Feresten now thinks that the joke, which became instantly famous, would not work in today's world. But back then it was no problem.

"It was a time in America when there were no real Nazis around. So it didn't really feel like that bad of a joke. But I think about it all the time," he said in an interview with The Washington Post.

Here's a fun fact for those who read all the way through. Jerry Seinfeld was actually banned from the real soup kitchen when he tried to visit the place after the episode aired.

Yeganeh got very angry with Seinfeld, screaming about how the episode had negatively affected his life.

And that's when the ban came. Quite fair, actually!
