sigh. Okay. Kerry campaign obviously knows Kerry can't listen to his hidden ear-mike (from his coaches) while simultaneously wondering if the blinking light is a supercoded message from his UN pals. No problem. Place the light on Kerry's tie pin.
I have a mobile DJ biz, and play live music. I have 4 sound systems,(small to rattle your fillings,) and you would be amazed at how hard it is at certain "venues" to get rid of unwanted noise or "buzz" that sometimes occurs coming out of the speakers,(ie neon, overhead lights, and sometimes even radio transmissions like police, CB etc.)
It would be funny if while they were testing his "ear piece",(if he tries to use one) that the timing light make his ear piece "buzz".......and now he can't use it !!
