Being a former prankster, I’d be tempted to go to supercheapsigns.com and order up some exact duplicates...but with one, imperceptible tweak: the line in Arabic would be changed to “Except for pig Muslim sons of Mohammed’s whore mother. Get off my lawn!”. I’d carry them in my car and switch a few out in strategic neighborhoods.
Ding! Ding! We have a winner folks!
