Look at what you've done
Really can't believe my eyes
Trading me for what?
Ha! Makes me laugh inside
Each day I see you two
My blood starts to boil
Baby, what's wrong with you?
(What's wrong with you?)
What were you thinking?
How could you choose her?
What were you thinking?
(Oh, oh, thinking?)
Are you out of your mind?
Remember who I am
Everything I gave to you
Now you walk around
With a cheap imitation
Getting mad just looking
At your foolish smile
Baby, lost your mind?
(Lost your mind?)
What were you thinking?
How could you choose her?
What were you thinking?
(Oh, oh, thinking?)
Are you out of your mind?
Ahhh-ah-ah!
(Your biggest mistake)
Yeahh-eh-eh!
(You'll regret this fate)
What were you thinking?
How could you choose her?
What were you thinking?
(Oh, oh, thinking?)
Are you out of your mind?
