you could do the giant obnoxious candy heart that i did for my ex last year lol.
its cute, fun, but just big and sweet enough to be left on his front door step and make him feel special :-)
there are many variations on the poem, but heres one:
My Dearest Sugar Baby,
Happy Valentine's Day! May this bouquet bring you a
Snicker as you read my message. You are my
Bit-O-Honey, you are worth more than a 100 Grand to
me, I get Goo Goo eyes every time I see you. There are
more stars in my eyes for you than in the Milky Way.
Our Good-N-Plenty life together is like shopping on 5th
Avenue on Pay Day. I know I can be Carefree with you.
As you know, I love you Now and Later and I wish you
Mounds of Almond Joy on this Valentine's Day.
Hugs and Kisses,
And here is a pic of mine (sorry its from my Twitter):
