This includes Bob Sacamano, an oft-referred to, but never-seen character, as well as Newman, played by Wayne Knight. Kramer is perhaps the most social of the four main characters, and seems to have more friends and associates than any of the others, some of whom are just as eccentric if not more so than he is. He also gets his friends into trouble by talking them into things such as parking illegally in a handicapped space (" The Handicap Spot") or urinating in a parking garage (" The Parking Garage"). Kramer never gets into trouble for it, but often his friends do. Instead of being horrified, many of these people end up thanking Kramer for his candor.

Kramer is known for his extreme honesty and lack of tact in " The Nose Job", he tells George's girlfriend that she "needs a nose job". On the other hand, he is often caring and friendly, going out of his way to get his friends to help others and to do the right thing even when they don't want to.

Described by an art patron as "a loathsome, offensive brute," he is often shallow, callous, and indifferent. Kramer has many conflicting personality traits. The backwards episode, " The Betrayal", explains that Kramer's original name, "Kessler", is just a misspelling on his intercom buzzer. Peterman." Kenny Kramer also made both monetary and non-monetary demands on Castle Rock Entertainment-all of which were met. In fact, the "Kramer Reality Tour" is itself spoofed on Seinfeld-when Cosmo Kramer receives money from catalog sales company owner Jacopo Peterman for the use of his various stories in Peterman's biography, he develops a reality bus tour and touts himself as "The Real J. His suspicion turned out to be correct Kenny Kramer created the "Kramer Reality Tour," a New York City bus tour that points out actual locations of events or places featured in Seinfeld. Larry was hesitant to use Kenny Kramer's real name for the fictional Kessler, because he suspected that Kenny Kramer would take advantage of this. At the time of the shooting of “ The Seinfeld Chronicles”, Kenny Kramer had not yet authorized the use of his name, and so Kramer's character is known as “Kessler”. Kramer's character is based on the real-life Kenny Kramer, a neighbor of co-creator Larry David.
