I had one on an 83 Toyota back in the mid 90's that said "Thanks for not Breeding" Some people did not like that. Usually got the most guff at Wal Mart parking lots...go figure.
Ha, I would take a pic of my new one. But its dark..It sas "NObama 08", but I think I should have got the one that said "we're ****ed 08" Since that applies to obama and hillary
