I had one2 on the back on my VW and when we broke down a very nice family helped us push it out of the way, the stickers were surfing related but only know in AUstrailia..." Dr Zogs Quick Humps Sex Wax" and in smaller writing, helps you get a better grip and another, a very common one was a picture of a man with a cockeril under his arm and of course "Man with Big Cock" there were others but I have forgotten at this moment. As it is common for VW's to have stickers in them I saw one that said "warning, women with PMT driving" I liked that...I shal have a think after my tea....
