I'd love to see some choice examples of graffiti any of y'all have run across personally. (ie, not stuff you've read/heard about)

One of my favourite examples here in Kingston, Canada, is on a wall in a narrow quasi-"street" called Opera Lane (it runs behind the Grand Theatre). It says:

Live your life forwards
Understand it backwards

I thought that was brilliant!

When I used to get hired by Queen's University in the art department (they are using models less and less, the ignorant sods), I used to really enjoy reading the cubicles in the women's washrooms, on any floor - fine arts majors seem to have witty/combative minds and a talent for expression....One day I saw a single serious question:

What is art?

I couldn't resist writing a frivolous response:

Art is a man with no arms and no legs, hanging on your wall.

I went to university at Trent in Peterborough, and the desks in the Bata Library always had great graffiti on them, too - wish I could remember some of it....I spent some serious study time copying it down but now I don't know where I saved it!
