One of my favorite exchanges from The Wild Geese:
(Roger Moore) - Allen! What, not even a hearty handshake, a Shawn my boy how are you, nothing?
(Richard Burton) - Clown
(Roger Moore) - Oh, "clown." At least it's a start. Now, would you mind telling me what you're doing here, thank god.
(Richard Burton) - If we live, I'll tell you about it. Idiot.
(Roger Moore) - Clown and idiot. You always were a flatterer.
