There’s a place with that same name in East Haven, CT. Or at least, there was (I try stay out of 'staven as much as I can).
I know a guy in Evanston who formed a small toolmaking company just for the name we came up with after several pints at Nevins’ : “Beecher Tool and Die”
He’s got cards, a sign on the building and has even done a few small jobs for locals.
Well, it’s a fairly obvious pun, so it may have arisen independently in each case. Or the inspiration could have gone either way.
My brother and I persuaded his (very religious) mother-in-law to name her second-hand shop “Needful Things”. As far as I know, she never picked up on the reference, and no one pointed it out to her before she shut it down a few years later.
Fluke Transport is a trucking company based in southern Ontario. Their slogan is indeed, “If it’s on time … it’s a Fluke!”
Bay City Screw and Bolt always gave me a chuckle.
There are Thai Me Up restaurants in several cities.
Found a screen capture from Blues Brothers with Fisher wearing a smock, with the salon’s name embroidered on it:
Near where I live is a branch of Sofa King. Slogan: Sofa King Cheap.
Honorable Mention: Apple Corps (Beatles)
Wisconsin Tourist Foundation had to change their name. :eek:
Oil company in Laredo Tx named Sanchez and O’Brian. Their logo was SOB. 
So did the City University of Newcastle upon Tyne. Allegedly 
(no bolding used in case I break board rules) 
“Welcome to Pen Island, the best place to get custom made pens on the internet!”: http://www.penisland.net/
Not the business name, but I recently saw a delivery truck with “Guaranteed Sex” in huge letters on the side. Turned out to be a pet store guanantees the sex of the animals it sells.
That is not a real company. It is a joke site. You can’t actually buy pens, or anything else, from it.
For a rather simple, one-note joke, that site has been around for a fuck of a long time. IIRC it was the 1990s when I first encountered it. It does not seem to have been monetized in any significant way, either. I can’t imagine the Google Adsense ads bring in much.
I always see lots of signs for Buttcon; it’s a big construction company in Ontario.
My mother swears that, when she was eight or nine years old, she attended a girls’ summer camp called Camp Little Notch.
a glazier here called "Pane in The Glass’
There’s a landscaping company here called Gardening Angels, which I think is darling. All these sweaty men, mowing grass and dumping horse manure around your trees: angels.
Along similar lines, there is a popular line of bottled beverages in Japan called Calpis, which we exchange students called Cow Piss. They were smart enough to market in the US under the name Calpico.

The Garden of Eatin’ diner.
I pass vans from this company regularly, but I still smirk every time: Beaver Maintenance.
I’ll just carry on looking after my own, thanks.
