I've always liked reading the dedication in books before I start them. Here are a couple I ran into this past year whose creativity made me smile.
from On Quaternions and Octonions by John Conway and Derek Smith:
This book is dedicated to Lilian Smith and Gareth Conway, without whom we would have finished this book much sooner.
from Nonplussed!: Mathematical Proof of Implausible Ideas by Julian Havil:
for whom my love is monotone increasing
and unbounded above
I can relate to both sentiments :)
