So anyhow, since most of you don't have a step mum, please change the lyrics as you please.

Did you know that you're the greatest _____ in the world?
If I ever had another
She/He could ever compare to you
You mean so much to me
How can there ever be
Someone greater than you?

******* to the greatest _____ in the world
You're the most amazing _____ there could ever be
You're the best ______ in history
But most of all, you're the greatest ____ to me

****** to the one who's always been by my side
The one who's presence, simply makes me want to smile
You're perfect to me just the way you are
Always striving to be better, you're only who you are today, so far

******* to the greatest _____ in the world
You're the most amazing _____ there could ever be
You're the best ______ in history
But most of all, you're the greatest ____ to me

Our time on earth is passing
We're getting closer everyday
To the end of our lives
So before I die I have to say

You're the greatest _____ in the world
You're the most amazing _____ there could ever be
You're the best ____ in history
But most of all, you're the greatest _____ to me
