Oh wow. I had to look up the last baby, I didn't realize that the actor who played Selvig was Alexander Skarsgård's dad. Small world.

Though I will say, I've always found it a little weird when parents marry spouses, who happen to be around the same age as their grown children.

It's like that one scene in "You've Got Mail" where Tom Hanks is introducing Meg Ryan to his aunt and his little brother (both who are under the age of 10).
