When Bob realized that Hiram and Mildred thought his project was about marriage counseling, he tried to back out gracefully. But their little family was SO bizarre and SO interesting in terms of how completely dysfunctional it was, curiosity got the better of him.

So he helped them discover what every other young married couple already knew - sex can be a heck of a lot of fun!

And that was fine for Hiram and Mildred, but then there was Gertie, Mildred's younger sister, who was also stuck in the house with the bizarre rules. Who was going to help Gertie find out what a normal sex life was like in modern America?

Well Bob was, of course.
