Peter Griffin: Your Honor, I call to the stand my surprise witness: The Ghost That Never Lies.
Peter Griffin: But only I can see him and hear him, so I'll tell you what he's doing and saying.
Child Welfare Agent: Objection, Your Honor! This is ridiculous!
Judge: Objection overruled. I'll allow it. You had better be going somewhere with this, Mr. Griffin.
Peter Griffin: Thank you, Your Honor. Ghost That Never Lies, did you witness the events that took place on that fateful day? You did. Well, how interesting. And do you see the culprit or culprits in this courtroom today? You do. Well, would you kindly point him or them out for this court? Don't point at me, you jackass!
