When I bought my first cameraphone I thought it would be useful not for sending MMS messages (especially not at 50p a pop) but because it would mean that I always had a camera on me to photograph those things that you would normally miss. One of the things I've looked out for since that date is some of the intelligent, witty and humorous graffiti that I stumbled across occasionally in the days before cameraphones. Some like the graffiti shown on http://www.latrinalia.org/. Unfortunately all the graffiti I've seen in the last 3 - 4 years seems to have been written by semi-literate, unintelligent fukwits. I saw one such example this lunchtime.

It reads: "Blow your self up you silly pakis muslims." and someone has replied "They r n taking your ass with them".
It makes me cringe.
my all time favorite graffiti (which i admit i've stolen and replicated many times) was written on a pub table in bristol.
some one had scrawlled, in typical pisshead fasihon
"I FUCKED YER MUM"
underneath which some one had added
"GO HOME DAD, YER PISSED AGAIN".
a true classic. (I especially liked the yer - they even do graffiti with an accent ;-))
