Some really good posts here regarding James's behaviour. He oozes low self esteem, immaturity, and at times low intelligence with the way he attacks people personally to try to "win" an argument. It's really pathetic, especially in front of so many other housemates. I'd hope some of them picked up on it too.
Another thing, George actually made me laugh at the end when he lightened the atmosphere with his "yo momma" joke, we need people who make a joke of things when you've got people with James's anger walking about the house. Though I did notice he said it when Audley finally shut James up and he looked embarrassed with the "I've won 31 times and I'm ok with that"
