You ever watch those house shows where two sets of neighbors trade houses for a weekend? Well, Mark and Abby are experiencing something like that: They're swapping bodies. But, unlike those shows, they didn't sign up for this. And there's only a month left until Abby… er, Mark's… due date! As if that weren't enough, Amazonia learns her fate, too. Excitement and laughs abound as the baby countdown comes to a close.
