Well, I'm assuming it's bs on some level. OP says in the later pages something along the lines of "1 million views, I feel like a proud father" Also for the fact that his status or w/e under his name says "brb, makin epic threads" and his sig has a url to the thread that says "remember the epicness" If that isn't enough evidence I don't know what it.
Now, as I said, it may be bs on some level... as this girls myspace with hella pics of her looks somewhat legit, I'm assuming that this joke is on her. Maybe she took these pics on the date in the pics, and her n the OP broke up or something and this happened, lol. I'm also not assuming that its her that posted in that thread as the girl in the pic, because I'm sure she wouldn't have linked to her myspace.
