He talks animatedly as he walks,
But there's no one near.
I glimpse a fang above his jawline.
Is he grinning from ear to ear?
Is he a raving lunatic?
My mind begins to fear.
Well, I'm relieved to tell you no.
That's his bluetooth headgear.
(I've been having fun with my LG Optimus One Android phone and BluAnt Q2 headset, hence the inspiration.)
