One Big Happy

In the series premiere, Luke and Lizzy have been inseparable since childhood. Now all grown up and in their 30s, the two housemates have decided to have a baby — in a rather nontraditional way. Lizzy, who is gay, is really ready to become a mom and who better to be the dad than her best friend, Luke. And Luke is all for it. Then, just as Lizzy discovers she is actually pregnant, Luke surprises her with the news that he has fallen in love and married Prudence, a free-spirited British beauty who was due to go back to England in a matter of days. Suddenly, a different kind of family is born and the three must learn how to make it work together.

On a group trip to the gym, Lizzy spies her secret crush, Kate (guest star Erinn Hayes – Childrens Hospital), and — with the help of Luke and Prudence — she initiates a conversation that leads to some plans for group bowling. Later, Luke and Prudence help get Lizzy an appointment with the best OB-GYN in the city and Lizzy is ecstatic until they arrive to a big surprise. Meanwhile, Prudence realizes she is feeling left out because of Lizzy's pregnancy and Leisha helps her explain these feelings to Luke.

The ever-adventurous Prudence convinces Luke and Lizzy that they need to spice up their lives, as their idea of a good time is tackling the Farmers Market each week. Fearing that his new bride will find him too boring, Luke takes a chance at skydiving — with some disastrous results.
