Fun With Numbers?

No.  Funny Numbers.

Catch-22′s original title was Catch-18. But shortly before it was published, bestselling author Leon Uris published a novel called Mila 18. Heller and his agent Robert Gottlieb didn’t want people to think Catch-18 was somehow connected to Mila 18, so they decided to change the number in Heller’s title. They tried out 11 and 14, but they weren’t happy with either one.

“After a halfhearted attempt at accepting Catch-14, Gottlieb had a late-night flash of conviction,” writes Eller. He quotes Gottlieb: “22, it’s 22! And I remember calling up Joe and saying, ‘It’s funnier than 18!’ But of course the fact is that no number is funnier than any other number, it’s complete self-delusion. But once we were convinced it was funnier, then it became funny.”
