I’m great fan of Wodehouse too. His work is quintessential British humour. I’ve read all of his Jeeves (a character from his book who is a butler) novels. Here are few dialogues from ‘The Code of the Woosters’ that I found humours:

1. “Good evening, Jeeves.” “Good morning, sir.” This surprised me. “Is it morning?” “Yes, sir.” “Are you sure? It seems very dark outside.” “There is a fog, sir. If you will recollect, we are now in Autumn- season of mists and mellow fruitfulness.” “Season of what?” (Opening scene. Conversation between the narrator Mr. Bertram Wooster and his neat butler Jeeves)

2. “There are moments, Jeeves, when one asks oneself, 'Do trousers matter?'" “The mood will pass, sir”

3. “I mean, imagine how some unfortunate Master Criminal would feel, on coming down to do a murder at the old Grange, if he found that not only was Sherlock Holmes putting in the weekend there, but Hercule Poirot, as well." ~ Bertram "Bertie" Wooster

4. “as if Nature had intended to make a gorilla, and had changed its mind at the last moment” Bertram describing Tom Travers

5. “She laughed - a bit louder than I could have wished in my frail state of health, but then she is always a woman who tends to bring plaster falling from the ceiling when amused.”

6. “You can’t fling the hands up in a passionate gesture when you are driving a car at fifty miles an hour. Otherwise, I should have done so.” Bertie Wooster to Jeeves when his provides solution to Bertie’s problem which he always does.

7. “If I might suggest, sir—it is, of course, merely a palliative—but it has often been found in times of despondency that the assumption of formal evening dress has a stimulating effect on the morale.”

8. “One frequently finds in girls a disinclination towards discussion of matter of importance”

9. Bertie: “Women often put a damper on things, don’t they Jeeves?” Jeeves: “They are brought up to believe that it is part of their duty to restrain male optimism, sir.”
