First comes baby then comes?

Riley's comment upon hearing the news of Bristol Palin's engagement to Levi Johnston was "How sweet." Bosco rolled his eyes. I said to Riley that Bristol's and Levi's relationship has been an ongoing news saga since Bristol's mom, Sarah, became an American household name. Also they were supposed to be married last year. They split up after Sarah was not elected vice president and since then they have been slinging around mud about each other and their families. But it's so sweet that now they're getting married, Riley insisted. Bosco looked up and with a certain amount of irritation and said, What's sweet is that Chelsey Clinton is getting married at the end of this month. The right comment for Bristol and Levi is, ITS ABOUT TIME. Riley looked confused. She wanted to know why he feels one way about Chelsey and differently about Bristol. Don't both their names start with C? Very funny, he answered. It has nothing to do with letters of the alphabet; it has everything to do with babies. They made a baby! What's the big deal Riley wanted to know. We dogs do it that way all the time.
