You think you've got it

Ohh, you think you've got it

But got it just don't get it

Till' there's nothing at all

We get together

Ohh, we get together

Then what makes, Then what makes, Then what makes
                                 C        F
Then what makes, Then what makes love the exception
C
So why you, why you
F
Why you, why you, why you are we so in denial
        G              Am
When we know we're not happy heeeerrreeee...

Hey Yah 
G   Am
Hey Yah  
(Slow strumming at the end)
C   F
Hey Yah
