Support Beetlejuice. His stage name derives from the 1988 Tim Burton movie Beetlejuice, in which a person in the afterlife had a shrunken head. The name originated from taunting Beetlejuice experienced at the hands of neighborhood bullies growing up in the housing projects of Jersey City, New Jersey. Green suffers from microcephaly, an abnormally small head and brain. Microcephalics, also known by the offensive pejorative "pinheads", have been featured in movies as early as 1932 (See: Freaks).
In Green's case, this condition is accompanied by mental retardation and small stature (4' 3"), though he does not have the disproportionate limb size associated with dwarfism. When asked about his height, weight, or pounds bench pressed, Lester will reply with a grossly exaggerated number. Green also suffers from depression and never gives any reasons why, which Stern and others are curious about.
Green had a running bitter feud with Hank the Angry Drunken Dwarf, but cried profusely upon learning of his death, calling him "[his] friend."
Green has appeared in films, including Scary Movie 2 and Bubble Boy, and provided guest vocals on the Smut Peddlers' album Porn Again as well as Lyrical Lizard's debut cd entitled "L.I.F.E.". He also provided the voice for the character Zeke in the 2005 video game True Crime: New York City; the character model in the game resembles Green. He has performed the songs "This is Beetle" and "I Don't Know," which were co-written by Stern Show staff member Richard Christy, who also provided the music and production. Staind and Blues Traveler have both covered the Beetlejuice songs. Staind plans to include their version  on their next album.
Since he is a favorite with Stern fans, Green has parlayed his fame by making personal appearances at various events. He also enjoys participating in dwarf tossing, in jurisdictions where the practice is still allowed.
On May 2, 2006, in a promotion for a Norelco shaver for male grooming, Green appeared on the Stern Show and had his scrotum shaved and then laid his scrotum on (or known by the slang term "tea-bagged") Australian porn star Jodie Moore. Later on, Green said that he was going to marry Ms. Moore and she could become Mrs. Jodie Moore Beetlejuice. Following that, Stern Show writer Sal the Stockbroker found a small pair of soiled underpants in the men's room and revealed Green had defecated in his pants before the tea-bagging segment. Sal brought the underpants into the studio, which Richard Christy wore on his head for $500. Christy reported that the smell from the drawers was "brutal" and threw up in a trash can.
