Short Circuit's Journal: Need examples of Bathroom Graffiti

For my film viewing and construction class project, I need examples of bathroom graffiti. Both from women's and men's restrooms.

Does it fall into general catagories? Artwork? Text? Personals? Preaching? Do some items of a given type typically prevoke a responding item?

Here's a few galleries

And I'm sure you can find several more in Google (just search for 'bathroom graffiti')
