Okay ladies, the first four B words in the dictionary are:

babble, baboon, baby, bachelor

The doctor said I was expecting a BABY,
I began to BABBLE like a mindless BABOON.

I'm single, I'm a good girl, no it can't be,
how can this be happening to me?

My folks will kill me, and what about Bill,
He'll lose it, how can I tell him to chill?

When I told him he got angry and slammed the door,
yelling he's no ones daddy, he's a BACHELOR!!!
