Just an odd pairing: on one side, Meat is Murder. On the other side, Pro-Choice
I once saw a motorcycle with a little tiny sticker on the back reading Start Seeing Geo Metros.
My uncle has one on the back of his truck that says
“This Vehicle Protected By Smith and Wesson”
I still get cracked up by that one.
I saw one in Florida one time that said
“No Officer, I’m Not Drunk, I Use the Beer Patch.”
Just when the WWJD craze really started to bug me, I saw
WWJD–He would stay right except to pass!
And I’m sure every computer geek out there has, at some time or other, cracked up at the sight of a “Feature” sticker on a Volkswagon.
I don’t have any bumper stickers, and I rarely pay much attention to them, but it is nice to see the occasional person going against the crowd with them.
I once saw a massive pickup truck with a Texas licence plate…it had a bumper sticker with one arrow that pointed to the left side that said “El Paso” and an arrow that pointed to the right side that said “El Cruncho” 
Mrs. Labrat and I were driving home when we saw an old beater car with a sticker that said, “I’d rather be riding my dildo”. The woman inside looked like a librarian! Another crude one was in a car driven by some teenage kid that read, “Let go of my ears, I know what I’m doing”.
I’m a pretty hardcore computer geek, yet I have no idea what you’re talking about. Care to enlighten me?
An ex-girlfriend of mine was fond of her DARE-lookalike sticker that said, “DARE to keep the CIA off drugs.”
I picked up a sticker at an Army surplus store at one point that said, “I <heart> Assault Weapons.” I put it on my car just to stir up the bleeding-hearts 'round here. I don’t even own any guns. One of my bleeding-heart friends suggested I also affix a sticker that said, “Arms are for Hugging.” I thought it was a great idea, but I never could find one after that. Damn.
It’s the canonical denial that you’ve made a programming error:
“It’s not a bug, it’s a feature.”
I should have specified that it was a VW Beetle, I suppose…
There’s a guy around here with three stickers on his truck:
“I love Celtic music.”
“The Goddess is alive and Magic is afoot.”
“My other car is a zamboni.”
I’ve always found that an interesting combination. “Harm none…unless he blocks your slapshot.”
One I saw back during the late, lamented, election:
“Vote Republican … It’s Easier Than Thinking”
What annoys me are those stickers that have a whole paragraph on them. Just how long do you want someone to follow you to read the whole thing? If it can’t be reduced to one line of few words - don’t put it on a bumper sticker.

Not a bumper sticker, but it was a sticker … from MAD magazine, back in the late 60’s, in one of their Special Editions (that cost 50 cents instead of 25), they had a bunch of stamps (no peel and stick back then), my favorite was (in pretty small type):
“By the time you finish reading this message, you will have made a complete fool of yourself by going around and around in this revolving door.”

“Save a turkey. Stuff an activist.”
Recently spotted: “My border collie is smarter than your Honor Student.”
Reminds me of the '49 Willys truck my brother owned with a licenseplate holder that read “My other car is a Porsche”. And it was! He was the second owner of a 924, until back surgery resulted in not being able to sit that low.
