Definately the dreamy time turtle commercial. The theme song goes like this: Dreamy time!!! Turtle time!!! Make a wish!!! AND GOODNIGHT!!! Now imagine an 80-something year old lady singing that while staring at kindergardeners who are aggressively hugging a stupid stuffed turtle. Yep, thats about right.
The Shake Weight and those backwards bathrobes (I refuse to mention them) had the worst dumbest commercials. The Shake Weight one was funny when I first watched it because it caught me off-guard, but the last commercial for the other product annoyed me because of the awful parody song they made.
