A masseuse bites patients' backs and bottoms.
Dorothy Stein, 48 - also known as Doctor Dot - lays patients on her massage bed and nibbles at their body before continuing with the more traditional oily rub, which she learnt from her mother at the age of five, and has a list of celebrity clientele including Kanye West, Keith Richards and Eminem.
Speaking to the Mirror online about her profession and her clients, which was first trialled on Frank Zappa in exchange for a free ticket to his concert, she said: "He [Frank] loves a gentle bite massage".
Dorothy began giving free massages but now the New Jersey physio charges $150 (£100), and is not fazed by unpleasant body odours or responses to her unusual sessions, although she won't bite breasts.
She explained: "I've seen it all and smelt it all. I've never bitten boobs though."
