What is Mother Father Chinese Dentist?
1.
Very obscure slang/substitute for swearing in frustration or anger.
Origin:
HBO television series
Mr. Show with Bob and David (1998 season 4, episode 5: It's Perfectly Understandable)
Sketch: Pallies (A Goodfellas parody, edited for television)
David Cross turns to Jay Johnston and yells (with terrible over-dubbed editing):
"Well you's can both grab one of my *books*,
you mother*father* *Chinese dentist*"
before shooting Jay in the head.
According to the Season 4 DVD commentary, years after the show ended, cast member Paul F. Thompkins had overheard someone talking on a cel phone in a bar utter the phrase "Mother Father Chinese Dentist!"
When asked if she was a fan of the show, her reply was "What?"
