Men and Women in Commercials

Why is it that women in TV commercials are always bossy super-bitches and the men are always whimpy idiots? What does this say about how our society looks at couples? Am I the only one who has noticed this? I give you for example the rug cleaner commercial where the husband is home watching his son and his wife says, "Make sure you don't make a mess on the white rug"...and while the husband is sleeping (while he's supposed to be watching the toddler)...the toddler dumps something red and sticky on the carpet. The man wakes up (good thing his kid didn't drink bleach) and rushes around to clean up the mess before his wife gets home and cuts his...uhm...yells at him like he's the child. He makes it just in time...once more he's put one over on the bitch he's married to who doesn't understand that accidents happen. Geez.
