One Big Happy

Best friends Lizzy (gay and a bit type-A) and Luke (straight and more laid back) are like family. When they were kids and both of their parents were getting divorces, they stuck together, and they've been there for each other ever since. Now, all grown up and still single, they've decided to start a family of their own. No, not like that (there are some lines even they won't cross) - we're talking the non-romantic, go-to-the-doctor's-office type of baby-making.
