My response:
In open court, you turn to the Assistant D.A. and say, "I'd like to drop the charges against my son."
The A.D.A. looks to the left, then to the right, then back at you, and says, "Are we on Candid Camera?" Then he just busts up laughing, "BWWAAAAAAAAHAHAHAHAHA". Then, the entire courtroom busts out laughing!!
