UTG Raise - KTo

What is it with KTo raise UTG. I have seen this happen so many times over the weekend that I have lost count. Is it the new AA hand that I am unaware of? I have seen so many players raise with KTo, seriously, not even suited? And they have actually followed on to a reraise behind! Does anyone out there think that more players are categorizing KT as a favorite hand and are mostly playing it or what exactly could be the reason behind it. Anyways, I guess KTo won around 80% of the time against the different hands I had seen dealt. From my end, hell no, I would much rather stay away from that hand. I read somewhere couple of months back that KT is one of the worst hands to play with even in late position and had put it in my mind. But now I see evidence contrary to that advice.
