What's the real title of that "proper young man's guide" book I saw?

I was at some vague acquaintance's house--obviously I forget whose--and he had this amazing book. It was something along the lines of "essential knowledge for every sterling young man!" It had the feel of spoofing a prep-school etiquette book for late-adolescent boys. But instead of entries like "how to politely ask a young lady to the theatre," they had stuff like "how to manage a date on the cheap." That entry I remember particularly well: it talked about over-chilling wine so that it'll be just right after a long walk, etc. There were also entries on all kinds of practical and less-practical stuff (e.g., common Latin phrases, etc.). Anyway, I know this is a shot in the dark, but I'd really like to know if anyone knows what book I'm talking about. I think the title may have included something about "rude" boys or rudeness generally, and it certainly mentioned the concept of essential knowledge. But a thorough amazon/library search has yielded nothing. Ideas?
