Who's sponsoring who?

My wife took me to my first AA meeting. I was in no shape to drive myself. It was a sunny Saturday morning in May, and since she had to drive me home, I asked her to join me. There were about 10 people in attendance that morning. Later, I discovered that they had changed the meeting format to a First Step meeting for the benefit of me, the newcomer. The first two gentlemen and one woman who shared, astoundingly, were all named "Bob."
