Why
do you build me up (build me up) Buttercup, baby
Just to let me
down (let me down) and mess me around
And then worst of all (worst
of all) you never call, baby
When you say you will (say you will)
but I love you still
I need you (I need you) more than anyone,
darlin'
You know that I have from the start
So build me up
(build me up) Buttercup, don't break my heart
"I'll be
over at ten", you told me time and again
But you're late, I
wait around and then (bah-dah-dah)
I went to the door, I can't
take any more
It's not you, you let me down again
(Hey,
hey, hey!) Baby, baby, try to find
(Hey, hey, hey!) A little time
and I'll make you happy
(Hey, hey, hey!) I'll be home
I'll be
beside the phone waiting for you
Ooo-oo-ooo, ooo-oo-ooo
Why
do you build me up (build me up) Buttercup, baby

but I love you still
I need you (I need you) more than anyone,
darlin'
You know that I have from the start
So build me up
(build me up) Buttercup, don't break my heart
To you I'm a
toy, but I could be the boy you adore
If you'd just let me know
(bah-dah-dah)
Although you're untrue, I'm attracted to you all the
more
Why do I need you so
(Hey, hey, hey!) Baby, baby, try
to find
(Hey, hey, hey!) A little time and I'll make you
happy
(Hey, hey, hey!) I'll be home
I'll be beside the phone
waiting for you
Ooo-oo-ooo, ooo-oo-ooo

anyone, baby
