Seen this one on a dodge neon,

MY KID IS AN HONOR STUDENT,
and MY PRESIDENT IS AN IDIOT

-and I don't know when it was put on.

some more:

BE NICE TO AMERICA,
OR WE'LL BRING DEMOCRACY
TO YOUR COUNTRY

and,
If you can read this,Thank a teacher
If you're reading this in English,
Thank a soldier.

or,
Turn the other cheek?
Hell, I Kick butt!

or,
Jesus is coming,
Look Busy

Disourage Inbreeding
Ban Country Music

I'm NOT Mooning you,
I'm turning the other cheek!

8 out of 10 voices in my head
say 'Don't Shoot!'

I've got a Perfect Body,
It's in the trunk and
starting to smell.

If any of those are repeats, sorry
