Gagdad Bob has compiled a list of Palestinian bumper stickers and comments:
Bumper Stickers of the Middle East
-Practice Premeditated Acts of Violence and Gratuitous Cruelty
-My Other Car is a Truck Bomb
-Jihad is Not Healthy for Infidels and other Vile Creatures
-Follow Me, I'm Lost
-My Son Graduated Summa Boom Loudly from Arafat High
-Pray for World Conflagration
-After a bomb lab was discovered in the Palestinian territories, I asked, "Isn't qualifying it as a Palestinian bomb lab redundant, like Bozo the clown?"
-There was a story about money laundering in the Palestinian Authority, to which I remarked, “Sources close to Arafat say that money was the only thing he ever laundered.”
B.S. UPDATE: Jonah Goldberg gives a list of Community Inactivist bumper stickers:
