This. On occasion I have resurrected a very old thread to post new, relevant information (such as the answer to a long-unanswered question in GQ) or to ask someone for an update on what was once a running story. When I do this I’m fully aware that the thread is years old, and even acknowledge this in the post. And yet the first few replies to such posts are usually zombie jokes. This is stupid and I wish people would cut it out. You’re not being clever by teasingly pointing out something that was writ large upthread. Even less so if you’re the fourth person in a row to do it, and are recycling the same tired zombie references that appear in countless other threads.
Once I was googling a subject, trying to find someone that agreed with me. There were two songs that I thought were uncannily similar but it felt like I was the only person in the world that saw it.
Then I found someone remarking on this in a google groups thread. Cool, I thought - I’m NOT the only one.
Then I sensed a …familiarity…in the google post. Not only did the author share my opinion, they sort of wrote like me.
Then I scrolled to the bottom. I saw a sig line. Then I realized I was looking at something I had posted in alt-fan.cecil adams over 15 years ago. The entire forum was migrated into google groups .
So I guess I WAS the only one.
The very first message board I joined was pro-zombie. If you posted a topic that had already been discussed last year, you’d be given a link to the old thread and told to post your thoughts there.
You know what’s fun about zombie threads?
You start reading one, come across a few banned posters, realize its six years old, then notice a few people who posted to it are online, right now! 
Speaking of being the “only one”.
I’m sitting here trying to wrap my puny mortal brain around those posts.
Aside from the novelty of someone returning to a deserted thread almost three years later to clarify a point (though it did not), or the fact that these two posts were the OP’s only ones, so much of it made no sense.
I remember when we didn’t even have characters.
We’d just go down the cave, paint an abstract representation of our OP in ochre on the walls.
I draw bison - dead bison - confused looking man in silly hat. They were all the rage back then.
I come back later and someone has written bison - hole full of spikes - dead bison.
Then, if it worked, I’d write back bison impaled on spikes - me with full belly - me burning offering to god of spikes.
Just a perfectly normal message board conversation with no ritualistic significance.
