I keep a few books made up of short things that can be read quickly. I take those with me to doctors' offices and other places where I expect to wait because I won't have to put them down in the middle of an interesting section when I'm called in for my appointment.
Recently, while waiting for a blood test, I was reading Richard Lederer's book, The Revenge of Anguished English. And I was silently laughing so much tears were running down my face and the receptionist asked if I was okay.
I was more than okay, I was having a wonderful time!
If you like slapstick or risque humor, Lederer's books probably won't strike you as funny as they do me, but I love language jokes and puns, so Lederer's books are my favorite kind of humor. The bun may be the lowest form of wheat, but I consider the pun to be the highest form of wit.
I'd read this book before, but pull it out to re-read every few years and it always makes me laugh.
And, since laughter is good medicine, maybe all doctors should keep copies of it in their waiting rooms.
