Haha, I think he was just kidding. I don't take much seriously on forums anyway, I could care less if someone dislikes me over the internet.
Does`nt sound like kidding to me, rather like when a rattlesnake rattles it`s tail - don`t even think it`s kidding or you`ve got problems.
Clint Eastwood would have "Made his day". Clint never even took insults about his mule in "Fistful of Dollars", it was case of "Get three coffins ready" and they sure were needed.
