I hate commercials that insult your intelligence.
The one that I currently find particularly annoying is the "Downy Ultra" spot where the hand is pulling clothes out of the bottle cap. The voiceover says something like "Can a little cap soften all this?" Well, if you count the clothes, it's a pair of socks and 3 shirts. I would ferdamsure hope that a cap of softener is going to soften 5 items of clothes.
