Oh, son of a bi-de-beh, son of a bi-di-beh, son of a bi-ba-di-ba-gun. Ha ha ha, you thought I was gonna say "son of a bitch," didn't 'cha?

- This Porky Pig cartoon

Examples:

• The above Porky Pig example.
• This commercial has a character saying what sounds like "dumbass," but it's really just a naive mispronunciation of the surname of the man he's talking to; Dumass. (Spelled "du-mah.") Then, at the end of the commercial, said man says "what a "dumbass" anyway.
• In an episode of Parks And Recreation where Tom is being more of a jerk than usual, Leslie, a character who rarely swears, says the following:
  "Look, I don't like to throw around the word 'butthead' often. If you call everyone a butthead, it kind of loses its impact. But I can say without hesitation that Tom is being a real dick."
