The Unbirthday Song

Statistics prove, prove that you have one birthday
One birthday, every year
But there are three hundred and sixty four unbirthdays
That is why, we're gathered here to cheer

A very merry unbirthday to you, to you
A very merry unbirthday to you, to you

It's great to drink to someone
And I guess that you will do
A very merry unbirthday to you

A very merry unbirthday to us, to us
A very merry unbirthday to us

If there are no objections
Let it be unanimous
A very merry unbirthday to us

A very merry unbirthday to me
(To who?)
A very merry unbirthday to me
(To you)

Let's all congratulate me with a present
I agree
A very merry unbirthday to me

A very merry unbirthday to all, to all
A very merry unbirthday to all, to all

Let's have a celebration
Hire a band
And rent a hall

A very merry unbirthday
A very merry unbirthday
A very merry unbirthday to all
