"Seinfeld" is widely regarded as one of the greatest series of all time due to its distinctive comedic style and its memorable cast. From main players like the quick-tempered George Costanza and the oddball neighbor Kramer to supporting characters like the conniving Newman and the digression-prone Mr. Steinbrenner, there's no denying the show has one of the most remarkable collections of characters in sitcom history. By focusing on the many antics and misadventures these characters get into, "Seinfeld" quickly became one of the most popular series of its day, and continues to enjoy critical acclaim decades later.
Given how many recurring characters fans see time and again on "Seinfeld," it's easy to forget how many smaller characters are sprinkled throughout the series. Sometimes, these characters are just as crazed and neurotic as Kramer and George. Other times, they're relatively normal people whose lives are practically ruined by their interactions with the main characters.
In many cases, these one-off characters are the highlights of the "Seinfeld" episode they appear in, proving themselves every bit as fun to watch as the main cast despite their limited screen time. Here are some of the best one-off characters to appear in the show's nine-season run.
