A couple of funny, famous quotes are: "Always borrow money from a pessimist. He won't expect it back," and "Dogs have masters. Cats have staff." A couple more famous quotes by renowned comedian George Cariln are: "Weather forecast for tonight: dark," and "Electricity is really just organized lightning."
Oscar Wilde's quote about borrowing money from a pessimist is interesting because of how it oddly makes sense. Pessimists generally have low expectations so they probably expect borrowers to keep their money anyway.
Another interesting quote is: "I love deadlines. I like the whooshing sound they make as they fly by." In this quote, Douglas Adams achieves humor by subverting audience expectations. Many readers may have expected the quote to be about respecting deadlines, but rather it is about disregarding them entirely.
George Carlin was a stand-up comedian who performed live shows for several decades throughout the late 1900s and early 2000s. Carlin was quite apt at observational comedy. His quote about electricity being organized lightning is funny because it is unique. Audiences relate to the topic, but never saw it in the exact same way. The Carlin quote "Always do whatever's next" is also funny because of its simplicity. It seems inspirational but is just basic, common sense.
