Ted L. Nancy

Under the pseudonym "Ted L. Nancy," Marder wrote a series of books containing excerpts of his prank letters, together with their responses. Books in the series include: Letters from a Nut, More Letters from a Nut, Extra Nutty! Even More Letters from a Nut, Hello Junk Mail!, Ted L. Nancy’s Afternoon Stories, and All New Letters from a Nut.^[5] Comedian Bruce Baum is the co-author of the first three books.^[5] In 2013, Scholastic published an historical Ted L. Nancy book entitled Letters From A Nut's Family Tree.

In 2002, ABC developed a pilot for a television series based on Letters From A Nut. It was written and produced by Marder and Seinfeld.^[6] In 2003 FX Television made a pilot for "The Ted L. Nancy Show." That show was written and produced by Marder and Seinfeld. Again in 2007, Lionsgate Television optioned the books from Marder to make into a television show, as reported by Daily Variety.^[7] The following year, Lionsgate sold the show as a pilot presentation to Fox TV. That show, called Sincerely, Ted L. Nancy, is created and written by Seinfeld, Marder and Chuck Martin. In the pilot, Ted L. Nancy (Kevin Sussman) is the voice for the underdog consumer who is usually the last to get help from customer service.

In April 2016, the first two episodes of Ted L. Nancy's SCAMMERS appeared on Hulu. The shorts were produced with Robert Redford's Sundance Productions. In these, Ted L. Nancy answers unscrupulous people who promise him great wealth through emails.^[8]

Ed Broth

Under the pseudonym "Ed Broth" (at one time thought by some to be a real prank author who submits joke letters to organizations and then publishes their responses), Marder wrote Stories From A Moron: Real Stories Rejected by Real Magazines, published in January 2005 by St. Martin's Press. The covers of the Ed Broth books show the title and author's name written childishly. The book comprises numerous prank letters the Ed Broth persona mailed to magazines along with their responses. One example is his essay entitled "I Love Dogs", that was sent to the publishers of I Love Cats magazine. The book's dust jacket description of Ed Broth states that "…[Broth] is a writer living in Toluca Lake, California. He likes pimentos in his potato salad".^[9] Jerry Seinfeld hosted a toast in his honor, although Ed Broth was not in attendance.^[9] Ed Broth's most recent literary project is a book of cartoons called "The Oddvious". Many believe the illustrator of "The Oddvious" is Alan Marder, who also illustrated "Stories From A Moron: Real Stories Rejected by Real Magazines"; "Letters From a Nut"; and "Hello Junk Mail!" by Ted L. Nancy.
