When Mark Schiff was six, his mother took him into Manhattan every weekend for singing and ballet lessons. When Schiff returned to school each Monday and showed his fellow Bronx classmates what he had learned, the class would gather around and beat him up. Schiff's mother smartened up and enrolled him in karate lessons, but those came to a halt when the karate teacher beat him up.

When Schiff was 12, his parents took him to a nightclub. There, live on stage was Rodney Dangerfield doing his act. At that moment, he knew the path he had to follow.

Schiff has headlined in all the major casinos and clubs across the country and has appeared many times on both The Tonight Show with Jay Leno and the Late Show with David Letterman. He has had both HBO and Showtime specials, and has been the featured act at the Montreal Just for Laughs Comedy Festival.

He has written for and guest starred on Mad about You, as well appearing on Empty Nest, and serving as a writer on The Roseanne Show. "Schiff is one of the funniest, the brightest, the best stage comics I have ever seen." - Jerry Seinfeld
