The Captain is in the House

We took the girls to see The Avengers. Shortly after the movie started Iron Man used a single swear word. Captain America said, "Language."
I leaned over and looked at the blond twin. She smiled.
Whenever I say something not meant for little ears, the blond twin says, "Language Mom." It's her trademark comment whenever she feels the need to let me know she doesn't approve of my word choice.
From the time we left the movie theater, Captain has been her new nickname. She requested it be shortened to Cap. It seemed like a reasonable request, so Cap it is.
