Off and on today, Jerry has been complaining about his neck. Yet, it's always at convenient times, and he usually does something right after that contradicts the extent of his pain. I have a feeling it's some dastardly plan he's created to save himself.
Yet it might be working. Memphis pointed out that he's in pain to Dan, who wisely wondered if he was faking.
Edit: Hahahahaha - since nobody was paying any attention to his ice pack, he disposed of it and started playing pool.
