Frank D'Angelo and Sidney
Sidney is so conniving and manipulating that even his family is not off limits. What must the Falco household be like at holiday time:
SIDNEY: Sorry Uncle Frank, no hard feelings, but a press agent's gotta do what a press agent's gotta do.
D'ANGELO: Sidney, you're my own sister's daughter and what you did to Steve was lousy, but we're family, so I'm gonna forgive you. Merry Christmas.
SIDNEY: And to you, too, Uncle Frank.
or maybe:
SIDNEY'S MOM: Aren't you going to say hello to Uncle Frank, dear?
SIDNEY (sheepishly): Hello, Uncle Frank.
D'ANGELO: Not this time, Sidney. Mary, let me tell you what your "wonderful" son did to his old uncle a couple of weeks ago...
This relationship give new meaning to the phrase "family with issues."
