Never one to miss an opportunity for picking up some extra spending money, Barney invests in stocks, records and rare nickels.

However, his biggest moonlighting project is in real estate. He has it all figured out: Mr. and Mrs. Simms will buy Andy's house, the Mortons will buy the Simm's house, the Clarks will buy the Mortons' house and Andy will buy the Williams' house. It's no surprise to anyone except Barney when the plan fizzles.
