From the episode Hughie Hogg Strikes Again... I can't remember the exact dialogue but its something like this. Hughie, dressed up as an old man has accused Cooter of stealing his wallet. Rosco tells Cletus to cuff and stuff Cooter. When Cletus moves in to do it, Cooter growls real deep and glares Cletus down. Cletus jumps back and whispers to Rosco, "Ya think he's had his shots?" Something like that anyway. I don't know if that should be considered a Cooter line or Cletus, but I think Cooter stole the scene. Ya don't want ta be messin' with ol' Crazy Cooter.
