They're definitely not two of a kind Have you seen this man? Ten-year-old Alex Harper is putting up posters everywhere. He wants to find his dad, but only so the judge can force the "deadbeat" to pay the support he owes. Maybe then his mother can stop working all the time, and she and Alex, his twin sister and little brother can finally take a real vacation together. To everyone's surprise, Alex actually finds his dad--or does he? The man calling himself Joe Smith certainly looks the part, but he claims there's been a mistake. And Frannie, Alex's mom, is willing to believe him. After all, he doesn't exactly actlike her ex-husband. Besides, it's said that everybody has a double somewhere. Of course, it's also said that twins run in families....
