I would love to have that happen to me. I would argue for jury nullification from the moment that we stepped into the conference room just to blast that judge back into reality.
Judges have basically unlimited power to throw people in jail for contempt. So I wouldn't recommend doing such a thing. Better would be to keep your toughts mostly to yourself, but if you felt you had to acquit someone against the judge's instruction, say you refused to convict because something "didn't smell right".
