Mr. Herriman

[Major Abbey]

That's basically what his role is, at least the way I see it; he's the one who enforces all these rules and tries to keep the house as civilised as possible. What's funny (again, in my opinion) is how over-the-top he is about it.

That's another one all the people who complain about him need to remember; his character does add something to the show, and it probably wouldn't be the same without him.
