I like the line you quoted, too, and was particularly struck by it this time.

My favorite bit, though, has always been (when Mr. Collins lists his reasons for marrying) "and thirdly -- which perhaps I ought to have mentioned earlier, that it is the particular advice and recommendation of the very noble lady whom I have the honour of calling patroness."

Isn't that what any woman wants to hear as a potential husband's most important reason for marrying?
