John Redcorn. For one, after Nancy and him ended their affair, he can still be seen at all the special occasions held by the Hills and other characters. Why would the guysinvite the man who slept with their best friend's wife to their parties? That's major back stabbing on their part for their friend Dale. Second, I just hate the man's morals.In "Peggy's Headache", when Hank confronts John Redcorn about treating Peggy, hetells Hank he "will not do to his wife what he does to the wives of others".So there's more married women he's slept with besides Nancy? I hope every man in Arlen whose wife has slept with John Redcorn finds out so they can form a mob and beat John Redcorn up. Couldn't he at least be a decent man and only give "migraine specials" to women who aren't in a relationship or married? Three, he is a show-off. When he used to come to Dale's house, he did the slow "catwalk model" walk down the driveway up to the door. And he always makes sure to walk in a way that the wind will blow his hair around. I bet I could rant even longer on why I hate his character.
BTW, I do remember Nancy finding out he slept with another woman and impregnated her the same night as her in "Untitled Black McCormack Project", but I didn't mention it because she wasn't stated to have been in a relationship or married at the time it happened.... But I guess you could say he still "cheated" on Nancy.
