It may have been on the vehicle itself, or it may have been a bumper sticker, but in whichever case it was in writing that would be about right for the phone book:
Trucks stay 300 feet behind
Bush - Like a Rock
only dumber
Nobody died when Clinton lied
“There’s a village in Texas missing an idiot”
I think I just hurt myself!
Cool! 
My favorites list is getting way too ling
Oops. Sorry Large Marge. I do love that one.

Also; “ling” = “long” in Berkeley.

I saw one today along the lines of “My wife is a font of sound advice. 99% sound, 1% advice.” Not that I particularly like it, but I thought I’d just throw it out there.

God Bless Lou Reed

i also like the darwin fish with legs applique
cheers,
My best friend got this one for his '67 Cadillac Hearse. It narrowly won out over “Shit Happens” and “I’d Rather Be Fishing.”
“My other car is a piece of shit too”
“Make love, not war. See driver for details”
“I love animals. They taste great” (A bit crass, but funny)
I didn’t like the following one, but I thought the ending was funny:
A car had “All men are idiots, and I married their king”. As I passed the car, I saw a man driving it. I thought that he must be an idiot for driving a car on which his wife had added that bumper sticker.
So, you assumed.
War stops a beating heart.
Long ago, on a busy roadway in New Jersey, I inadvertently ran over a small animal (opossum). After my initial feeling of remorse for the newly compressed marsupial, I was overcome with embarrassment, realizing that the people behind me, reading my recently applied bumper sticker, were certainly drawing a logical conclusion about my nefarious driving agenda. The soon to be torn off bumper sticker read:
Caution, I speed up to run over small animals

Escape FROM Wisconsin
A satire of the “escape to wisconsin” tourism slogan.
Stop Global Whining
A satire on global warming.
All on the same car;
Isis! Isis! Ra! Ra! Ra!, Ankh if you love Isis, and GOP does not spell God.

(not true, but I still laugh every time I see it hanging up in this prof’s office)
When I was about 19 or 20, I had two stickers on my car that I loved. One was the famous:
Don’t like my driving? Dial 1-800-EAT-SHIT
and
Moody bitch seeks kind, considerate
guy for love/hate relationship
The scary part was how often I got approached and hit on because of the second sticker. “Hey, where do I apply??”
“I support the right to keep and arm bears.”
“Death before Dishonor. Nothing before Coffee!!”
“We need some old time religion! HAIL ZEUS!”
“My son and my money go to Texas A&M University.”
After all the Jesus Fish, followed by Darwin Fish, Fish eating other fish, Cthulhu fish, and the like, I have to admit that I really like the Christian Fish outline that has, written within it:
GHOTI.
There are a lot of very witty bumper stickers available from Nancy Buttons, saying the same things as the buttons:
