"Yes Sir, That's My Baby" brings back Susan Lawrence as Sally Friedman, extremely pregnant in "A Mommy for Morky," now a happy mother with newborn son. Mork finally meets the former bulge when Sally walks into the record store, exulting in the tiny life form and wondering when he can get one of his own. Unfortunately, a lowlife character (Will Porter) has followed Sally around and now brazenly offers Mork a proposition, his own baby for $10,000. Although Mindy jokes that she only has the kind of money that jingles, the FBI gives her that exact amount, ready to pounce on the thief once the deal is made at the bus station. Mork learns the truth about the infant's true parentage, but has experienced the joys of fatherhood for one hour.
