"Rhubarb and tonic" is what the crowd says on tv during a din in the courtroom when the defendant is proclaimed guilty or innocent because it provides the best sound mix.
Judge: I find the defendant guilty.
Crowd: (general din)

Judge: Order! What are they all saying?
Dick Wolf: Your honor, I believe they are saying "rhubarb and tonic"
Director: Yes, that's what we told them to say. This is what is called a "rhubarb and tonic moment".
