no help to you for just making a joke, and you guys wil have heard of this one for ages, but I once read a book where the author thanked this way....
"and finally, I would like to thank my wife for staying up with me as I revised drafts upon drafts, but most, I'd like to thank my two lovely chidren X and Y, but for whose help this book would have been finished at least two years ago.
To them, with love, I dedicate this book"
