Stars: Katherine Heigl, Seth Rogen

What's appealing here is the notion of fate, and that there are no accidents. Maybe the fetus Heigl and Rogen conceive by mistake was meant to be. Maybe these seeming opposites are soul mates. Maybe it's when we're at our least responsible that we are at our most intuitive. The message to women is clear: Sleep with a man in your immediate vicinity, as soon as possible, because he could be the one.
