I like all of them.
But I gotta say something about the biggest bullshit forum of BSN. The Sewer once was a great forum that contained the best of jokes and well thought out ways of having fun.
But nowadays things have gotten old and boring. The jokes that used to be so great are being dragged on and on as if they'd still work. The forum is exploding with retarded jokes of sexual nature that once were fun to see here and there. But now, I find it nothing more but a big pile of annoying crap that lost it's value. It's predictable and it's lacking originality in every corner.
So taking that into consideration, then the Sewer would be my least favorite forum right now.
