Getting Laid: A New Hallmark Niche Market?

I thought they made greeting cards for every imaginable occasion, but as I discovered recently, there are no greeting cards with which to congratulate a friend who has just gotten magnificently laid for the first time since the traumatic end of a major relationship over a year ago. That being the case, I had to make do with what was available: one of Hallmark's Cinco de Mayo e-cards. So after my friend's new lover left--after she changed the sheets on her bed, smiled at her ridiculous bed-head in the mirror, applied various lotions to her newly chafed nether regions, settled in with some coffee to read her email, and gave me the low-down on her hot date--she got an e-card featuring a mariachi band playing some wildly festive tune while the words "Sing... Dance... Celebrate" appeared on the screen. So the card actually wasn't all that off the mark, but still. Hallmark? Can you say "untapped market niche"?
