Inspired by this post in the Pit thread on feeding raccoons.
Brilliant post. Incisive, informative, tough-minded, and devastingly logical. My only comment in response to it was that it was the best damn post I’ve read this year.
Which raises the question: what would you nominate as the best post ever–or at least in a currently active thread? You may wish to differentiate by forum, as a A++++ GD post is vastly different from a A+++++ CS post, IMHO post, etc.
Any nominations?
Grandpa is trapped in The Maxtrix, by Scylla. In MPSIMS, though not MPSIMS. At all.
^^^Yeah, that was a very good one.
I think all of my own are gems, of course. 
I think the greatest post has yet to be discovered.
Though there is this post, which is certainly a diamond in the rough.
You’re so predictable. No wonder Annatar was able to escape your custody.
I don’t think I’d be able to find it. I don’t know who posted it, nor in which forum, but my Clue guess is Qadgop in CS with the candlestick. He was not the OP, but it was a thread about LotR. Someone had asked why Gandalf was a wizard when he obviously never cast any spells. The post in question ran for about three pages. It was epic. I laughed, I cried, I soiled myself, I took a shower, I did some laundry. It was a true work of art.
Tell that to your colon. By Auto, perhaps?
I felt that this OP was a perfect encapsulation of the frustration that Euthanasiast was feeling about a former relationship. It still brings a small tear to my eye.
I can’t search for the link, but Eve’s post with the “Gotcha ya!” was the reason I kept lurking here for so long.
In this thread, Qadcop makes a LOTR post so geeky, his fellow geeks don’t know what he’s talking about and assume he’s just making fun of them. That is damned impressive.
A week after I joined the SDMB four years ago, I read this GQ thread, which asked
I was particularly amused by post #14 by pravnik, who, after writing a couple of authoritative paragraphs about the legal status of Gozilla, concluded:
Four years later, it’s still my favorite SDMB line.
As SNenc said a few posts earlier:
Well, that just made my day. 
Giraffe’s post here is my all-time favourite.
I’ve long been fond of this post.
Is it threadshitting to say that this thread made me glad I renewed again?
That is awesome.
I’m almost afraid to look at this post again, because I truly am not worthy to bask in its glory and beauty, but hands down, this post had me in tears for…well…it’s a year later and I’m still crying.
Hmm, I guess I’ll be the first to post this classic about telemarketers.
Skald the Rhymer, I’m honored to be included with the likes of ‘Grandpa is trapped in The Maxtrix’ and ‘this classic about telemarketers’. Thank you.
