Andy Kaufman’s best friend and co-conspirator Bob Zmuda had plenty of great stories when he sat down with Marc Maron for his WTF podcast. But arguably the best story Zmuda told was about the three weeks he worked for legendary screenwriter Norman Wexler (“Joe,” “Serpico,” “Saturday Night Fever”) in the early 1970s. Kaufman apparently got a lot of ideas (especially for his obnoxious Tony Clifton character) based on Zmuda’s tales of working for Wexler.  Zmuda reveals how Wexler really got his knack for writing intense, gritty dialogue.  Hilarious, jaw-dropping stuff, especially the tale about Wexler and Zmuda terrorizing a bakery.  This incident sounds like it was lifted from a Lars Von Trier film starring Sacha Baron Cohen, but it really happened, according to Zmuda. Not safe for work. If you like what you hear, you really need to read Zmuda’s terrific 1999 book “Andy Kaufman Revealed” which delivers more Wexler tales, as well as tales about Kaufman.
