Is this a good place to start another thread on graffiti? It's just that I heard about such a good one the other day... I live close to a university, and the area is known for having somewhat intellectual try-hards living around here. Anyway, a friend of mine went to her corner store (see another thread about that!) and saw that someone had spray-painted "Question everything" on the wall. The owner will eventually clean it off, but for now has added "Why?"

alexis, that's great! I'm trying to think of recent ones...

meanwhile, welcome back!

I remember a series in one of the toilets at my old school back in the '70s. Don't remember the whole series but it started with someone proclaiming that everything that God makes dies, going through some claims that Jesus was an exception to this statement and ending with the penultimate graffitist being called a monophysite heretic.

Thanks, AnnaStrophic!

Another good one - this from my German teacher back at school - apparently a fave of German kids:
Goethe ist tot
Schiller ist tot
Und mir geht's nicht so gut...

Goethe is dead
Schiller is dead
And I'm not feeling so well...

OK, alexis. That one reminds me of (also back during my college days):

"To do is to be" - Camus

"To be is to do" - Sartre

"Do be do be do" - Sinatra

we all personalise our wheelie bins round our way and the german bloke next door has painted 'ich bin bin' on his.

And who can forget the classic pair:

God is dead
           -- Nietzsche

Nietzsche is dead
           -- God

?

...or the one from the ladie's restroom:
"My ex-husband follows me everywhere."
Beneath which is scrawled:
"I do not."

My favourite has always been the one I saw in pub toilet:

Watney's beer is like making love in a punt: both are ******* near water."
