A Washington Post Competition's Romantic Rhyme

A Washington Post Competition asked for a rhyme with the most romantic first line, but the least romantic last line. This is the winning entry:

My Darling, my lover, my beautiful wife,

marrying you screwed up my life.

I see your face when I am dreaming.

That's why I always wake up screaming.

Kind, intelligent, loving and hot:

This describes everything you are not.

I thought that I could love no other:

This is until I me your sister.

Roses are red, violets are blue,

sugar is red, and so are you.

But the roses are wilting, the violets are dead,

the sugar bowl's empty and so is your head.

I want to feel your sweet embrace

but din;t take that paper bag off your face.

I love your smile, your face, and your eyes,

damn, I'm good at telling lies!

My love, you take my breath away

What have you steeped in to smell this way?

My eelings for you no words can tell,

except for maybe 'go to hell!.'

What inspired this amorous rhyme?

Two parts tequila, one part lime....
