Answer: He installed asbestos in schools. It's not said what he did after that, but he complained about all his work being undone.

Answer: Hank is portrayed as being somewhat stern and uncomfortable with expressing a lot of deep emotion. Maybe it's because of the way his father, Cotton, treats him: scolding him for acting too emotional and such. This is shown in some flashbacks. A recurring joke is that he has no problem being "lovey dovey" with the dog, Ladybird, and easily shows his affection to her.

Answer: I don't think this has been explained in any episode. At some point, he most likely asked people to use his full name. Perhaps he wants to highlight the "Redcorn" at all times, out of pride for his family history.

Answer: John is a common enough name that they might know several other Johns that we've never met, so they're being specific.

Captain Defenestrator

Answer: It's not uncommon in real life for spouses to be unhappy in their marriage and resort to extramarital affairs. I haven't seen every episode of this show yet, but the vibe I get is that it's not so much funny that she cheats on Dale, but how painfully oblivious Dale is to it, to the point where he can't even tell Joseph is obviously John Redcorn's son and not his.

Answer: Nancy has stated that she loves Dale "in a 'lights-on' sort of way" (season three - "Peggy's Headache"), and other episodes make it clear she cares about him. It could be a case of her "having the cake and wanting to eat it, too." She can enjoy her affair with Redcorn while Dale takes care of Joseph, due to him not always working much. Perhaps she needs an escape from Dale's reckless adventures and conspiracy theories. An affair is not a good way to deal with this, in my opinion, but there are people who do it.
