Sanya Weathers, no stranger to the MMO industry (or breasts, for that matter) just recently took a pretty funny tour of how breasts work into advertising, whether we like it or not.

If you're up for a laugh, go check out her article over at MMORPG.com. It's funny, it's insightful, it's historical, and it's full of what men want most -- awesome games. (Get your head out of the gutter if you thought that last line was going to be another boob joke.)
