Kenny Kramer - Seinfeld

Michael Richards did not want to meet with Kenny to study the character and wanted to create the character himself. This situation was later parodied in the Seinfeld fourth season episode "The Pilot". The character was originally going to be named "Kessler" (parodied when he and Jerry are shown meeting for the first time in "The Betrayal"), due to Larry David's fear that using the name might spur the real Kramer to exploit his association with the character. However, Jerry Seinfeld thought that the name was too good not to use. Kenny Kramer then proceeded to contact Castle Rock Entertainment with a list of several demands, many of which were financial, for the use of his name. One demand not met was that Kenny would get to play Kramer, which is also parodied in "The Pilot".

Kenny has been the host of Kramer's Reality Tour and Kramer's Reality Road Show for the past 13 years. He tells behind-the-scene Seinfeld stories to his audience and gives a bus tour of sites made famous by Seinfeld. A DVD version of his reality tour has been produced. The "Reality Tours" were later parodied on Seinfeld in the episode "The Muffin Tops", when the Kramer character receives money from catalog sales company owner J. 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. Peterman." The relationship between Cosmo Kramer and Kenny Kramer is explored in the featurette "Kramer vs. Kramer: Kenny to Cosmo", on the 3rd season Seinfeld DVD.
