For their Valentine’s Day promotion, Sprint needed a retail site to showcase their phones. Of course, phones aren’t all that romantic. Or are they? People hook up over the phone. Flirt over the phone. In fact, phones are like little tools for love.

This thinking inspired the Tools for Love online kit: a kit that not only featured phones but also contained a few other romance-inducing tools, like the Seductive Serenader, featuring Isaac Hayes, and the Txt Romantifier. With the Seductive Serenader, users could write lyrics and Isaac Hayes would sing them real sexy-like. Once satisfied with their serenade, users could send it to a loved one via email or as a phone call. Conversely, the Txt Romantifier allowed users to add romantic prose to their texts with the press of a button.

During the 3-week promotion, users spent an average of 3 minutes on the site, over 100,000 Seductive Serenades and Romantified Texts were sent and 57 children were conceived.
