Billy Goldberg, M.D. (now called “Dr. Nipples” by the nurses’ aides with whom he works) is a practicing physician at Bellevue Hospital and NYU Medical Center. Billy would like to make it clear that he and Leyner do not do medical experiments on each other. He is also a painter whose work has been exhibited in New York City.

Mark Leyner is the author of five books including ET TU BABE; MY COUSIN, MY GASTROENTEROLOGIST; AND TOOTH IMPRINTS ON A CORN DOG. He has written scripts for a variety of films and TV shows. Next time you see him he’d be happy to tell you what it was like being on the Montel Williams Show with mutant dogs and a psychic.
