The Friars Club Encyclopedia of Jokes

I got this book as a birthday present, which is fine, I like joke books. This is indeed, an encyclopedia of jokes, at 500 pages, organized alphabetically by topic. Some are contributed by famous members of the Friars Club, others are unattributed. But imagine my surprise when I stumbled across a joke I wrote in the book! So, this book was published in 1997, and back in 1992, when I was working at Bellcore, I submitted this questionable joke to rec.humor.funny. And what do you know, right there, on page 95, there it is. It's a crazy world when a book written 20 years ago has a joke in it that I wrote, and I never even knew about it. I'm not sure I'd call it an honor, exactly, the majority of jokes in this book are pretty weak ("If exercise is so good for you, why do athletes have to retire by age 35?"), and many of them are painfully racist and sexist. Some I liked, though:
"Do you suffer from arthritis?" "Of course, what else can you do with it?"
"How do you know when there's a singer at the door?" "They can't find the key and they don't know when to come in." 
"It's not an optical illusion... it just looks like one."
In any case, I got an interesting story out of it!
