You needed me when you were crying,
But now you're laughing I'm the last thing on your mind.
First you love me, then you don't.
I'm up and down,
Like a yo-yo.
Yo-yo.

Ah, you thought you knew me pretty well,
But with people like me you never can tell.
You can only guess which way I'll go.
You got me sussed, but you don't know,
I'm a yo-yo.
Just like a yo-yo on a string.
