According to this 1950's etiquette guide I found, a hilarious Parlour Game is asking people to name famous Belgians.

The point of the game is that there aren't any. I have:
King Leopold
Tintin

Which is not a great list is it. It's not really much of a game, either. That kind of game is quite fun though, like where you ask people to name all the famous Scottish people they can think of, or the most famous birds, or whatever. I was walking back from getting coffee just now, and thinking about all the celebrity horses I could name. I had:

Seabiscuit
Red Rum
Secretariat
that horse of the Aga Khan's that got kidnapped
Alexander The Great's horse
Dick King's horse called Somerset

There are actually lots. It's a good game. If you play that game, and someone says Secretariat, then you can say, "Did you know that Secretariat's groom was called Eddie Sweat?", and then they can say, "Oh Gross."

It's true. That celebrity horse called Secretariat had a groom named "Eddie Sweat". He is the subject of a book called The Horse God Built: Secretariat, His Groom, Their Legacy.

I would actually LOVE to read this book. I know that I would read the whole thing in like a DAY.
