I had to remove my 12" “Steal your face” sticker since it was falling apart, but now my car is adorned with one grateful dead sticker, a small sticker that says “PIMPMO” (an inside joke), and a giant “Paintball Authority” decal with the number of the shop on it. Glad I got that off my chest 
Short and to-the-point: Caution: Stunt Driver
I don’t have any bumperstickers on now but there are two that I think would be good ideas:
“Sona si latine loqueris”
and
“Honk if you’re moderately fond of Jesus”
Visualize Whirled Peas
Two that I’ve seen and want, but haven’t found where to buy yet:
Have you tormented the Devil today? and
Where are we going and why am I in this hand basket?
I got a new one a few days ago it says “one by one the penguins steal my sanity.”
My truck has “My other car is a {tank symbol}”, which is appropriate.
none on mine, but I saw two on the same car I liked:
Madness Takes its Toll
Please Have Exact Change
I don’t suffer from insanity, I enjoy every minute of it!
BTW, what is a “head store”? That where they sell shrunken heads?
“Head shop” = a place where smoking paraphernalia is sold with large signs claiming “for tobacco use only” even though nobody in the history of the world has ever smoked tobacco with them. Usually also sells t-shirts, magazines, posters, and other smoking-related accessories.
I have only one message on my vehicle, a smallish rectangle in my rear window that reads:
We are at war with Eastasia.
We have always been at war with Eastasia.
It’s quite amusing to see people pull up behind me, lean forward, squint, and stare blankly, knowing they sort of recognize what they read but unable to remember exactly where, and therefore struck with uncertainty about what, precisely, it’s supposed to mean.
I make my own at work, one says
"Free Tibet - limit one per customer, while supplies last.
the other says:
“** I’m an asshole And I Vote!”
I change them as I get bored with them.
“It’s called thinking. You should try it sometime.”
And one that I want someone to make, a spoof off of those stickers on trucks:
“How’s my driving? Call 1-800-DNT-CARE”
Oh… hmmmm. I have a few I guess.
- Pearl Jam sticker (blue with the ape/man evolution insignia)]
- U2 sticker that looks like one of those oval European country’s stickers.
- “Don’t judge a book by its movie.”
- Pink Floyd (just the words)
- Darwin fish

Mine are all band stickers.
Minor Threat, Weezer, the Cure, Rancid, L7 and a Pearl Jam that I need to put on as soon as I find a little time to wash the back window and stick it on.
“Howard Stern is God”
“Mean people suck, Nice people swallow”
I have yet to actually put it on the Jeep though.

That is all
