My lazy eye.

I went to see the doctor, And she said my eye was lazy. I must confess I thought that she Must be a little crazy.

She said Right Eye was really strong, But had a lot to bear, 'Cause Lefty was a little lax And didn't do his share.

She said since Righty seems to be The one who always hustles, We'd let him rest behind a patch So Left would use his muscles.

So now when someone sees my patch And says to me, "What's wrong?" I tell them Right Eye is on a break, And Lefty's getting strong!
