...but I have not heard this before.
Recently, there has appeared a bunch of bus stop posters for Comcast Sportsnet that all have the form of "I don't know where [x] is [or are], but I know where [local sports team name] are" (e.g., "I don't know where the Ferry Building is, but I know where the Giants are"). And I've been seeing these ads every morning because I take the F-Market to work every day, and there is one of these posters on Market Street every few blocks.
I ran a search on "I know where the A's are" and found that there has recently been at least one commercial on Comcast using this same form -- it shows what kind of looks like the Marin Headlands where a man is standing and wearing a blue tux jacket but no pants, who says, "I don't know where my pants are, but I know where the A's are," followed by a graphic reading, "Authentic fans know."
Okay, I get the joke. And I'm guessing that I never saw the commercial because I never watch any cable sports channels.
The thing I don't get about all this is the poster on Market Street in the vicinity of Seventh Street that reads, "I don't know where the Tenderknob is, but I know where the A's are."
The poster got it right: I don't know where the Tenderknob is.
I ran a search on "tenderknob," and I found a few references, like this blog. So I guess Comcast didn't make the name up as a joke.
Is this just a new cutesy way to refer to the Tenderloin? Is it an area between Nob Hill and the Tenderloin? What's the scoop? And how long has this term been around?
And why am I always the last person to hear about these things? :-)
[UPDATE: It really read "Tendernob," not "Tenderknob" with a "k". See my subsequent update.]
