"I wanted her so bad, and I didn't know why," Todd says. "She abused me, but it's almost like this dominance thing. So we had ridiculous sex the next day. I thought that was it, but I went back! It was a little embarrassing. My friends were like, 'You went back to her? You're crazy.'"

For Nashville songwriters Josh Kear and Chris Tompkins, however, the jealous girl is a muse. That Carrie Underwood song about the girl who thinks her boyfriend is cheating and takes a "Louisville Slugger to both headlights"? That's right—"Before He Cheats" was written by a couple of dudes. The fact that it went multiplatinum, won a Grammy in 2007, and is now a karaoke standard for many American women makes a pretty convincing case for the American male's enduring fascination with—and affection for—the jealous female.

"I used to have a joke," Kear says. "Whenever I find a woman jealous enough to fill a car with wet concrete if I cheat, that's the woman I'm going to end up with." Doug might have a solution: His crazy ex-girlfriend Kerry is still single.
