JR might get to work RAW next week, as a farewell, and maybe the WWE will let Jim Ross and Jerry Lawler work together for events such as inter-promotional matches, and the like, and maybe host PPV preview shows on WWE.com, or something, but I don't think we'll see JR and King back together full-time on RAW again.
Although, I could very end up wrong. Not going to take a $100 bet from Rob, that's for sure. So, to put my technical vote in, KK: 7 days.
