When it comes to creating memorable characters, the sum of "Seinfeld"'s parts is more than its whole. In fact, the following "Seinfeld" characters have become so familiar to television audiences that the mere mention of their names evokes a smile and a knowing nod.

Susan Biddle Ross

George’s wealthy fiancee (Heidi Swedberg) -- and one-time NBC programming executive -- met her untimely demise after licking the toxic glue on the cheap invitations George selected for their wedding. She dated George for quite a while before deciding to step out with members of the same sex. However, Susan's change in lifestyle only served to heighten George’s attraction to her, and the two became reacquainted. After her death, George was asked to sit on the board of the Susan Ross Foundation and was stunned to discover just how much money she was worth.

Another nemesis of Jerry’s, Kenny Bania (Steve Hytner, NBC’s Working) is also a struggling comedian. Although Jerry derisively calls him a hack, his stand-up routine about Ovaltine makes audiences laugh. Generous by nature, he once gave Jerry an Armani suit in exchange for a dinner at his favorite restaurant. Earlier this season, Jerry referred to the performer as a "time slot hit" when Bania was offered his own television show after finding success when he followed Jerry’s act at a comedy club.

J. Peterman

A suave chap who finds much pleasure in ornate use of the English language, some fans might say the character of J. Peterman (John O’Hurley, The Edge of Night) is based on the real catalogue magnate of the same name. Peterman first hired Elaine as a copywriter for his catalogue when the two met on a New York street and she impressed him with her adventurous prose. Since then, he had Elaine run the company while he took an extended visit to Burma; he purchased JFK’s golf clubs and a piece of the Duke and Duchess of Windsor’s wedding cake at auctions, and bought life stories from Kramer for use in his autobiography. He regularly hosts an annual party for his employees at which Elaine never fails to embarrass herself -- either with her dancing or by making out with a co-worker.

David Puddy

Patrick Warburton (Dave’s World) first appeared as Jerry’s car mechanic and dated Elaine until she discovered that he stole Jerry’s secret sexual "move." After breaking up, the two reunited in the Season Nine opener when they traveled to Europe together. The unstable couple sometimes breaks up several times in an episode. Puddy, who is partial to fur coats, recently made a career change and joined a Saab dealership as a car salesman.

Jerry’s ill-humored Uncle Leo (Len Lesser) resides in New York City where he drives his nephew crazy. Leo is remembered for keeping both a watch and a wallet he found in a garbage can, putting Nana (Billye Ree Wallace) in a retirement home and, most recently, shoplifting books.

Mr. Pitt

An affluent businessman, Mr. Pitt (Phil Morris) served as Elaine’s boss for some time. He is perhaps best remembered for eating a candy bar using a knife and a fork, making Elaine scrape salt off his pretzels and sending Elaine to represent him at a very important meeting because he was caught up staring at a poster which had a hidden image in it.

Poppie

Poppie (Reni Santoni), the older relative of one of Jerry’s many girlfriends, once became partners with Kramer in a unique pizzeria business and astounded Jerry by not washing his hands after using the restroom. He is perhaps best remembered for his uncontrollable bladder problem while sitting on Jerry’s couch.

Tim Whatley

As Jerry’s dentist, Tim Whatley (Bryan Cranston) helped originate the term "re-gifting" when he gave a label maker to Jerry that Elaine had previously given to him. Jerry also suspected that he lived out a few fantasies with an attractive hygienist while Jerry was under anesthesia. Most recently, an annoyed Jerry became convinced that Tim converted to Judaism so he could tell Jewish jokes and still be politically correct.

Mickey

A struggling actor and good friend of Kramer’s, Mickey (Danny Woodburn) has faced a few problems courtesy of his tall friend. Kramer brought shame to the short-statured Mickey when he convinced him to put lifts in his shoes to gain a few inches. The two were embarrassed when they double-dated without determining which one of them was interested in which woman. He also got Kramer a job acting out various illnesses for medical students. At Mickey’s wedding last season, Robert Wagner and Jill St. John played his parents.

Crazy Joe Davola

Crazy Joe (Peter Crombie) is a borderline insane writer who falls for Elaine and stalks her in a clown outfit when she doesn’t return his affections. During his numerous appearances, he also swore revenge on Kramer, who failed to invite him to a party, and Jerry, whom he believes intentionally wrecked his deal with NBC.

Ping

The delivery person for a Chinese restaurant, Ping (Ping Wu) has been involved with the group on several occasions. He’s translated a call to a doctor in the Orient who claimed to have a remedy for George’s baldness; refused delivery to Elaine because she lives on the wrong side of the street, and threatened to sue her when her jaywalking caused him to have a bicycle accident.
