Mindy brings home a record of Robin Williams' "Reality, What A Concept" and notices that Mork greatly resembles the comedian on the album cover. Mork doesn't see it but the people in Boulder do because they think he "is" Robin. Robin happens to be coming to Boulder for a live show and Mork is nearly trampled by crazed fans. Mindy gets to interview Robin and brings Mork with her.
Mindy has to work late hours on a new TV call-in show, "Talk to Dr. Lincoln", so she asks Mork to help with the housework. When his cleaning efforts turn the apartment into a disaster area, he calls Mindy on the air for advice and nearly gets her fired. When Mindy asks Dr. Lincoln for advice on how to help Mork adjust better to her working, Dr. Lincoln suggests they do a role reversal exercise - so they switch places.
