Yep, Merle's a moron. Only he would choose to cut off his own hand instead of either cutting through the bolt the handcuff was attached to on the roof or cutting through the handcuff itself.
That hacksaw probably wouldn't be able to cut through the cuff links all though I personally would have tried before even thinking of cutting of my hand.
His brother is as big an idiot as he is.
Gotta feel sorry for Shane. Why wouldn't he think Rick was dead if the hospital had never been evacuated or as it was over run with Zombies. I would have thought the same thing especially given Ricks medical situation.
Are they calling them Geeks? Hilarious.
