From the movie Wedding Crashers... Vince Vaughn gets in a "situation" with another guy who wants to play "Tummy Sticks"...
You ain't figured shit. I can't just create the post under someone else's name. I can only edit or delete. So, you must have posted something in this thread. Do you remember what it was, if it's not the post that's currently there?
Not saying this happened, but if it did, it's pretty damn funny. You can "move" or "copy" a post from one thread to another, just make sure you take one of the posts at the right "time stamp" and it'll fall into place perfectly, then you may edit at will, and all loks normal to a regular user
That's a lot of work to put into a joke. You would have to be pretty devious mofo to put it in that kind of effort. Personally, if I were to commit such an act of mischief, I would use post from whoever had already posted in the thread. Anything beyond that would be too much work. Hypothetically, of course.
