First, disable any filters (moderate safe search and the like) you may have on google search - I think these should be off by default anyways.  If no kids have access to your computer and yet you prefer to self-censor google search results, I suggest you take a long, hard look inside your soul and ask whether you really want to be one of those sorry people who think it makes sense to expend energy in avoiding accidentally reading the word 'fuck' or seeing an uncovered breast or two. In other words, get a life.

Now type 'my girlfriend' on google and check out the search suggestions it gives you. As of writing, these include 'cheated on me', 'is fat', 'hates me' (most search results by far), and 'is a virgin'. A martian trying to understand human nature in a hurry would be wise to use google search suggestions over any treatise on the subject I can think of.

And if you thought that was revealing, try typing 'my girlfriend won't', for suggestions such as 'shave'. Absolutely brilliant, absolutely spot on.
