Lyrics:

Well...
I really do hope that it's a boy,
But I wouldn't mind one of the kind,
It really would fill my heart with joy,
Fighting in the buff, to get him really tough.

We could be happy you and you and me,
That's when one plus one can equal three.

La la la la la la la la la la la la la la la.

Well...
I really do hope that it's a girl,
But a little knob would really do the job,
We'd have to get used to the smell,
Of getting mucky hands, changing mucky pants.

We could be happy you and you and me,
That's when one plus one can equal three,
Three of four! Maybe more!
That's when one plus one can equal,
Four, Five, Six, Seven, Eight, Nine? One more time!
That's when one plus one can equal three!
Yeah, yeah.
