Across multiple episodes and seasons, Kramer (Michael Richards) tells Jerry (Jerry Seinfeld), George, and Elaine (Julia Louis-Dreyfus) about a friend of his named Bob Sacamano.
Despite the abundance of information about the character, Bob never makes an appearance in any episode of "Seinfeld." Bob Sacamano is first referenced in the Season 2 episode, "The Heart Attack," in which George ends up in the hospital. He hasn't suffered a heart attack, but it turns out he needs his tonsils extracted, to which Kramer objects, citing his friend, Bob Scamano. "He came in here for a hernia operation...Now he's sitting around by a window, in a chair, going" — and here, Kramer launches into a whiny, high pitched voice — "'My name is Bob!'"
After that, the Bob Sacamano references appear nine more times across the show's run, with the last mention appearing all the way in Episode 20 of the final season. During the course of the show, we hear that Bob's synapses were too large for shock therapy to have an effect on him, that he's working in a condom factory, and that he has rabies. Truly a renaissance man, this Bob.
Eventually, Jerry attends one of Bob's parties and becomes friends with him, making it all the funnier that we never get to see him. The last we hear of Bob is that he made his fortune by inventing the rubber strings on paddleballs. For the show about nothing, it feels fitting that one of its most memorable characters is nowhere to be seen.
