Leave It To Wodehouse
Pelham Grenville Wodehouse wrote some of the funniest books in the English language. Ask anyone who has read one of them.
Sarah gave me one of his books a couple of years ago, my first. I grabbed it when leaving for the doctor's office to read in the waiting room. Well!
I was trying so hard to stifle my laugh I was gagging and the tears were running down my cheeks when a nurse came out to ask if I were ok. Such a combination of hilarity and embarrassment I hope never to experience again.
If I remember correctly that book was Leave It to Psmith (1923.) In any case, that’s a good place to start. As is any of his other hundred or so books.
