For those of you who, like myself, are addicted to multilingualism,
here's a book you you might enjoy as much as I do: 

PARDON MY SPANGLISH by Bill Santiago www.billsantiago.com
One man's guide to speaking the habla.

Why do I recommend this book? Simple: ¡Porque because!

Or, as the author himself says: Life's too short to be monolingual.
