dumb as dirt

Some guy on Craigslist thinks corporate America has brainwashed people into showering daily.

My argument: you don't need to take a shower every day. You just don't. I know some will attack me for this statement, and may even try to call me out as a slovenly, smelly loser somewhere trying to argue away my greasy skin. Well, I'm not. I'm a well-dressed, good looking early 20's guy, work downtown in the loop, etc. But lo and behold, I don't take more than two showers a week and do just fine...

...See, its all about getting manipulated, and most people in the US have bought it. Soap companies, cleansers, shampoos, and more toiletry products than you can name all want you to take showers every day and use up their products, so you can buy more.

Yes, that's the evil advertising industry for you. Selling people on useless concepts like bathing. We suck.
