For me it was the legendary, Where did “Nuke 'em from orbit” come from?, thread which swiftly degenerated into one long list of Aliens quotes as applied to a message board. I still re-read it occasionally when I need a laugh.
Sorry I don’t have a link, anyone else, what thread convinced you to sign-up?
For me, it was probably a GD thread about religion and/or the existence of God. I was really into debating that topic back when I was in high school - not so much anymore; I think I’ve heard virtually every argument for each side.
I wandered in after reading the Dope Archive and I commented on two columns. After that I wandered through the SDMB and found I really liked it. So it was no specific column.
It was the “What if The Lord of the Rings had been written by someone else?” thread that brought me here. I think it was a couple weeks later that I actually joined.
It was this thread: The “Garfield” Where Jon Drinks Dog Semen. It made me laugh so hard that my dogs started barking at me. I knew had to be a part of a place that could make something as lame as “Garfield” so much fun.
Same here. It was linked in an LOTR thread in DVDTalk.com, I clicked on it, loved what I read, read the other threads in Cafe Society, loved those too, joined up.
Scylla’s Sperm Count of Doom thread was probably the first thread I ever read here. After wiping the tears of laughter from my eyes, I realized that this would be a good place to hang around.
I can’t find the link now, (it’s amazing how many posts have the words “dead dog and pool” in them) but it was a thread where someone was asking for help because he woke up one day to find a dead dog floating in his pool.
He came here to ask for some advice on how to remove it.
As soon as I read the thread, I knew I had to join just in case something equally unexpected happened to me and I had no idea where to turn for advice.
