And it's not that cake... 

You get three guesses as to what these women are doing. And why it's so important.

In case you couldn't tell by the wedding cake (that we so clearly pointed out to you), these two lovely ladies exchanged vows when gay marriage became legal in California yesterday.

And why are they so important?

In San Francisco, Del Martin, 87, and Phyllis Lyon, 84, longtime gay rights activists, were the first and only couple to be wed here, saying their vows in the office of Mayor Gavin Newsom, before emerging to a throng of reporters and screaming well-wishers.

Ms. Martin and Ms. Lyon, who have been together for more than 50 years, seemed touched, if a little amazed by all the attention.

“When we first got together we weren’t thinking about getting married,” Ms. Lyon said before cutting a wedding cake. “I think it’s a wonderful day.”
