Girlfriends are like baseball teams...

I was getting a ride from someone on my softball team when we got in a discussion about choosing a favourite baseball team. He originally liked the San Francisco Giants and the Oakland A's equally, but since then has decided to root solely for the A's. He was explaining it to me like this:

"Choosing a baseball team is like choosing a girlfriend. When you have two girlfriends, your heart will eventually tell you which one you like better..."

I couldn't have put it better myself!
