There was an Australian Play - the ABC did a Radio version of it and I was involved with a group doing it at one stage - called "Bill Stickers will be prosecuted"

Ok these two aren;t specifically grafitti, were clever anyway...

There was a Scuba Diving shop in Toowoong called "Come Diving"...

and a hamburger shop near the Enoggers Army base called
"The Taik Hawaii" (say it out loud with an Aussie nasal whine)...
