I’ve been here a couple of months and have come across folks referring to the topic. I figure it’s probably a reference to an inside joke known by everyone who posts here EXCEPT ME! So, give, huh? 
Dammit Snowboarder, you got your wish.
To the OP, Snowboarder Bo (likely the only person you actually saw saying this) liked the quote from The Office and tried to make it a thing around here, ended up being more of a catchphrase for him with the exception of a few other people saying it mostly to make fun of him.
Okay, answered in one. No need to actually go down there.
Snowboarder Bo can correct me if I am wrong. But, he didn’t pick up on the quote because of The Office episode, but because of a very funny (possibly untrue) story that someone posted on the boards. I can’t remember who posted the story, but the person claimed that he changed his boss’ autocorrect so everytime he typed in LOL it was corrected to “Let’s go down to the quarry and throw stuff in there!” And, since the Boss typed that a lot, it ended up driving him crazy. Hilarity ensued.
Ah, it was Chessic Sense.
Ah, thank you all. Failed catchphrases strike me as a special kind of sad. Which gives me an idea for another thread. Hang on.
Along with many others…
Overall, I’d say it’s not popular with most posters saving Bo.
Sheesh. I didn’t know I’d be reopening THAT can of worms.
Sorry for dredging up bad memories. Sort of like finding something you don’t like in the bottom of a deep water-filled pit that some bored person just threw in there.
Okay, that was probably wrong. Sorry.
Wrong? Meh. Appropriate? A+!
Hi-fuckin-larious, ain’t it? :rolleyes:
In Snowboarder Bo’s defense, other than the aforementioned lame attempt at starting a ‘meme’, IMHO, he seems to be a decent sort and his postings are usually, fairly rational and intelligible. 
Not popular? I think it’s frickin’ hilarious.
Wanna get a six-pack and go down to the levee?
Six-pack? Whiskey and rye is the preferred drink in that location. 
How about asking about avatars next?
I drove my Chevy down there but the levy was dry.
There were some good old boys there, but I was so drunk on the whiskey and rye, I forget what they were singing…oh well, not important
I drove my Chevy to the quarry, but it was full of random shit.
As I said repeatedly in both the ATMB and the Pit thread, it was never a goal of mine for it to become a meme or a catchphrase; it’s just something that I found funny and it makes me laugh (yes, out loud!) every time I see it. So I went and set my computer, my phone and my iPad so that whenever I type those three letters, the devices change it to Let’s go to the quarry and throw stuff down there. It still cracks me up!
This is correct; I first encountered it in Chessic’s post.
Thanks!
You’re welcome.
Hey everybody! Loach wants to ask about avatars!!
Yeah, like I was going to fall for that one? 
[TMI alert]
[I’m writing this because stupid thread drift is allowed in ATMB and because inscriptions on the Internet ostensibly are forever, and some things just must be made known for future musicologists and students of The Human Condition.]
I, on the other hand, will never forget that song because it was droning its interminable epic storyline–with the LP player in fucking repeat mode to boot–while I, for the first time, was going down on a girl, who was unwashed and decidedly rank down there. Caring sexual provider and explorer of all things novel, I soldiered on, ruefully assuming, incorrectly, as I later happily learned, that that was the way it was supposed to be.
To conclude this memorial, I can’t remember her name, but although not pretty she was nice. I met her in Hebrew School.
So now it has been written. Future generations, you’re welcome.
