My favorite (paraphrased):

Attorney: “You are absolutely certain that [victim] is dead?”

Coroner: “Yes.”

Attorney: “Were you there at the time of death?”

Coroner: “No.”

Attorney: “Then how can you be sure they’re dead?”

Coroner: “Well, their brain is sitting in a jar on my desk, but I suppose the rest of them could be out practicing law somewhere.”
