Foolproof, that's what my heart's become
And I challenge anyone to break in
I challenge anyone to make me open up the door
'Cause I've been fooled before
And now I'm
Foolproof, older and wiser now
And I'm never gonna fall for that old
Never gonna fall for that old fairy tale anymore
'Cause I've been schooled before
And 'cause I'm foolproof
And I dare, anyone to try
Not a care in the world have I
As long as I am foolproof
Oh no, they can't fool me
'Cause I've been around the block a few times
Been around enough to know, I'm coming back for more
'Cause I believe that your heart is pure
And 'cause I'm
Foolproof
That's what my heart's become
