This thread has a lot of spoilers.
When you first meet Kenny, he tells you that his son is stupid as a bag of hammers. Kind of cruel to call your own son like that. I never liked Kenny starting from the beginning because he left Shaun for walkers, which made me think that he is as stupid/coward as his son. Thus I sided with Larry during the Duck dilemma. But well during the second chapter of second episode, I found out that his wife calls him stupid as bag of hammers as well. This made me laugh because I thought the same and she said exactly same thing as he said about his son. And later he proved his stupidity by smashing Larry's brains.
So here you can discuss whether Kenny (and his son) deserves this title of the "Bag Of Hammers"
