Most annoying Joseph A Banks Clothing...an over the top announcer and the frequency makes these commercials my candidate for most currently annoying.
Close behind...The Phillips Probiotics commercial with ath "Matron of Honor' doing a bridal toast(?) and praising the virtues of Phillips. If I was in the wedding party she would have been shoved into the nice body of water in the background.
There are a ton of commercials on the air that after I have watched them, mostly by accident, I wonder, "What the hell were they selling anyway." I have to wonder who the writers are aiming for in their quest to sell product. Did I ever write a bad commercial, YOU BET, but fortunately it was a long time ago and all traces are now hurtling through space to convince other life forms that there is no intelligent life on earth.
