Lyrics:

This is a song that I wrote you for your birthday
Because I couldn't be bothered to buy you anything
And I know that you might think that
Writing this song required more effort
Than going out and buying you something
But I can promise that it didn't
I'm not even going to include your name in this song
Because that way I can use it on somebody else
And if you listen closely then you might be able to tell
That I only bothered using three chords
I guess that just shows you how much I care

Happy birthday insert name here
Congratulations on living another year
Only joking I did get you something
And it's right here
