I've never actually listened to the entire "On your feet..." commercial - dude sounds like a constipated old man with a mouthful of urine-soaked cotton - I mute or fast-forward the second I hear his "Attention!" - I don't even know what he's selling...and don't really care.
The #1 worst of all FTL commercials - in my opinion; is the irritatingly perky woman with the "your family today" tips - every time I hear her voice, I feel compelled to spit or drop a deuce - if I could actually force myself to listen to the commercial, I would be sure to avoid purchasing whatever she's selling.
Old "Attention!" fart man is the #2 worst FTL commercial for me.
The "How long can you hold your breath" commercial is #3 - though I dig the product and will probably purchase it eventually...I think he's the dude selling the water filters? Anyway; don't ask me a question and then answer it for me - how the hell does that douche know if "not long" was gonna be my answer? I can hold my breath for a pretty good bit, but that doesn't have good G-D thing to do with whether or not there's weird shit in my water. A better question to begin the commercial might have been; "How much weird shit is in your water?"
Lastly, #4 worst for me is Ian's voice doing the commercial that begins to name off all the random shit you could get at Amazon - I dig Ian; he's cool for a smarmy jackass, but his advertisements make me want to start a mosh-pit at work while Mark's stuttering, randomly syncopated ad-reading style is somehow soothing.
