TV Shows... with the adoption theme.

I've noticed that a lot of the shows I watch have introduced adoption into their storylines. Now, this could be a case of the "new cars" — meaning that it seems once I get a new car (or am about to), I notice them everywhere... when, in fact, it's a case of just being more aware of them. That said, I feel like there are a bunch of adoption storylines out there right now! It's a continual storyline on: • Mad Men

• [the new] 90210

• Brothers & Sisters

It's also been mentioned on a couple of other shows I watch, including House M.D.

Any others I'm missing?
