Editing Cosmo Kramer (section)

==Pseudonyms==
Like the other three characters, Kramer has [[pseudonym]]s he uses in various schemes.

Under the name H.E. Pennypacker in "[[The Puerto Rican Day]]", Kramer poses as a prospective buyer interested in an elegant apartment in order to use its bathroom. Kramer also appears as Pennypacker to help Elaine get revenge on a [[Maya society|Mayan]] clothing store, "Putumayo", by repricing all the merchandise in the store with a pricing gun in "[[The Millennium (Seinfeld)|The Millennium]]", though due to a mishap with the pricing gun, Pennypacker instead removes the [[desiccants]] from clothes in the store in order to render them "noticeably musty in five years". In this latter capacity, he claims Pennypacker is "a wealthy American industrialist".

In "[[The Nose Job]]", Kramer uses the pseudonym Professor Peter Von Nostrand to pose as the betrothed son-in-law of an incarcerated man who once stole his jacket in order to retrieve it from the man's apartment; Kramer's jacket, to which he attributes at least some of his amorous success, is a minor plot point in other episodes until, in "[[The Cheever Letters]]", he trades it to a [[Cuba]]n embassy official for several boxes of authentic Cuban cigars. Later on, he more famously adopts a similarly named alter-ego, Dr. Martin van Nostrand (in addition to "von" instead of "Van", "Nostrand" is also pronounced differently in this alias). As Dr. van Nostrand, Kramer tries to get hold of Elaine's medical chart to erase the negative comments her doctor has made in "[[The Package (Seinfeld)|The Package]]". He also uses the van Nostrand alias in the episode "[[The Slicer]]", posing as a "[[Juilliard]]-trained dermatologist" for a cancer screening at George's company, Kruger Industrial Smoothing. Mr. Kruger later recognizes him as Dr. van Nostrand in "[[The Strike (Seinfeld)|The Strike]]". Kramer uses the name Martin van Nostrand (without the "doctor" title) while auditioning for the role of himself on the show ''Jerry'' in "[[The Pilot (Seinfeld)|The Pilot, Part 1]]".

Kramer is also occasionally called "the K-Man" ("[[The Barber (Seinfeld)|The Barber]]", "[[The Bizarro Jerry]]", "[[The Busboy (Seinfeld)|The Busboy]]", "[[The Note (Seinfeld)|The Note]]", "[[The Hamptons (Seinfeld)|The Hamptons]]", "[[The Scofflaw]]" and "[[The Soup Nazi]]").

A derogatory designation for Kramer has been "[[Hipster (contemporary subculture)|hipster]] [[wiktionary:doofus|doofus]]", a moniker assigned to him by a woman in a wheelchair he once dated in the episode "[[The Handicap Spot]]", and occasionally directed at him by Elaine, as in "[[The Glasses]]". The nickname was first used in [[The Atlantic Monthly]] review of ''Seinfeld''.<ref>{{cite web|url=http://www.stanthecaddy.com/seinfeld-episode-guide/|title=The Handicap Spot|quote=[I]n this episode, Kramer was referred to as a "hipster doofus", which is an inside joke Larry David wrote in response to a review of the series by Francis Davis that appeared in the December 1992 issue of The Atlantic Monthly. In the review, Davis describes one of the characters as "Jerry's across-the-hall neighbor, a hipster doofus known simply as Kramer."|publisher=StanTheCaddy.com|access-date=Jun 16, 2009}}</ref>
