Come on, commercials

I've had a few issues with commercials I've seen tonight.

First off, why did Special K have to cast a super skinny girl in a commercial that's main point is you should drink their 5 calorie protein water instead of eating so you can lose weight... I hate complaining about this because it's always whined about, but seriously. What were they thinking?

Second, these pharmaceutical ads are getting even more ridiculous. One of them is for some bowel disease and warns that side effects include flatulence. I so did not need to know that. It also seems to suggest that the medication might not work all that well. Also, can this prostate medicine please think of a less gross motto than "It's your growing problem, shrink it"? Please?

Finally, I just saw a public service ad in Spanish while watching Colbert, which is, 90% of the time at least, in English. Why are all those people who need to get their public services in Spanish even watching it...
