"Mork's Baby Blues" opens with Mork passing out hundreds of dollars at the New York Deli, all of which came from the board game Monopoly, celebrating an evening of victory over Mindy. Kathy Cumberland (Dinah Manoff) walks into the deli and listens to Mork's boasting, believes he's worth a fortune and shows off her gold digging personality by inviting him home for dinner. Her attempts at seduction don't go as well as she'd hoped, asking him to do something fun like remove his suspenders: "that's no fun, I do that every night!" After crashing on Kathy's couch, Mork returns home to a furious Mindy, who spent the entire night worried sick about her absent friend. She wants to know why he responded favorably to the dinner invitation: "I was hungry!" Revealing that he spent the night with Kathy (now claiming to be pregnant), a jealous Mindy is even more surprised when Kathy shows up to insist that Mork give her money to handle everything, only for his willingness to marry the girl pushing her to the brink of madness (Carl Gottlieb doing the honors). Mr. Bickely offers a bit of constructive criticism: "this is the stupidest thing you've ever done!"
