Political statement making bumper stickers ftw. There's a hippie store I love that has them all over a wall
That reminds me of one that I saw a few times a long time ago (I used to see it advertised in National Lampoon) NUKE THE WHALES And it showed this whale with a little mushroom cloud in the middle of it-guess they don't make those anymore.
My personal favorite says: "I'm trying to see things from your point of view but I can't stick my head that far up my ass."
"I used to have superpowers, but my therapist took them away" Somebody here has a pic of a car with that sticker on it in their sig.
I haven't read through all of these, so I'm not sure if this one was mentioned: "Don't tailgate me! or I'll flick a booger on your windshield" hahahaha
