It was more like 15 years ago, biqu – reason I know, I was living near VA (in Maryland), and dating a woman whose divorce was being finalized.
She had researched the laws, and claimed that Virginia had laws on the books that would have made us criminals if we’d stopped for the night – we thought about printing up bumper stickers correcting the slogan: Virginia is for some lovers.
There’s a BBQ place here in Topeka called Boss Hawg’s. I love their slogan.
“Horrifying vegetarians since 1995!”
There’s a demolition company in Baltimore whose truck are emblazoned with the motto, “We Destroy Everything We Touch.”
Must have laughed for five minutes when I saw that.
There’s a Native territory in southern Ontario inhabited by the Wahta people. A store was recently built. Now, when you drive through the reservation the sign gleams like a beacon in the night -
What A Convenience !
It thrills me every time. Wahta great sign !
There is car repair shop that advertises fairly regularly on the radio in the Boston area. Their motto is “We will brake, shock, and exhaust you”.
There’s a fence company in Raleigh, Seegar’s, with the motto: “Dependable Erections since 19XX.”
Too bad for Pfizer.
Worst - On all the vans of a local ‘Custom Drywall Company’ is this one:
“J.R.'s Custom Drywall - We’ll Rock Your World”.
Oh, hahahaha (not)…I get it. You’ll rock my world…with Sheetrock. Oh, you’re killing me.
LAME!
“A Dry Crack is a Happy Crack” is on a lot of our public buses in St. Louis. I think they’re advertising that they’ll fix cracks in your house’s foundation, but the first time I read that, I lost it.
Sofa King…
Our prices are Sofa King low! 
(I win! give me the prize!)
A sewage company in a nearby town has “USED FOOD HAULER” emblazoned on the bug shields of their trucks.
I like it.
Well, not really a slogan, but…
There’s a local lawyer who advertises on the radio. The first line of the spiel says, “When you’re looking for an attorney, you want someone who will work on your case for you.”
Well no shit.
From the Jack Schmitt car dealership in Illinois:
If you don’t know where to get the best deal on a new Chevy, then you don’t know Jack Schmitt.
I had a coworker that had a bumper sticker on the back of his car advertising a muffler shop. Dave’s? Bob’s? Anyway it read:
Dave’s Mufflers
No muff to tough
We dive till 5
Porky’s BBQ runs an ad on TV here in southern Oregon: Hand rubbed meat can’t be beat.
There was a BBQ joint here called Southern Yankee. Their motto was “Eat here, or we’ll both starve.” The business went belly-up, and it’s now called Baby Bear’s.
Three doors down the street, Fox Radiator Service has, since 1967, been “The best place in town to take a leak.”
Albea Plumbing sponsors a bowling team. The shirts say, on the back, “Your sh_t is our bread and butter.”
A couple of times during my commute I’ve seen a delivery truck for a coffin manufacturer. Emblazoned in large letters on the back of the truck is “Drive carefully - we’ll wait!”.
In downtown Atlanta there used to be (may still be, for all I know) a bakery called “God, Jesus, the Holy Spirit and Our Bakery”. Absolutely the best cakes and cookies in town. The only problem was that you never knew in advance when they would be open or what they would have. The owners said “We open when God tells us to, we close when God tells us to, and we bake what God tells us to.” I wonder if my boss would go for that?
I just saw an amusing one for the local racetrack.
For BeaveRun Motorsports complex…
“You haven’t raced until you’ve lapped the Beaver.”
