Auf geht's, Jeeves!

The book is filled with witty language and comic situations. I'm curious how much was planned versus evolved naturally during writing.

Jeeves's unflappable demeanor is iconic, but I wonder if that made the chaos around him even funnier or a bit too unrealistic.

The portrayal of high society is both satirical and affectionate. Did Wodehouse base it on real experiences or purely from imagination?
