The rules are simple, someone posts something and everyone tries to figure out what it is. It can be anything, but it should be something that most if not all the forum members can get right. Don't post something like Navier Stokes equations (for the record I have no clue what that is I just Googled complex equations).
The first person to get the answer correct gets a cookie and is the one who will post the next. If someone thinks they got the answer right but they were actually wrong, their item should be ignored and return to the previous item on the list. The person that thought they were right will receive: a potato. If no one is able to get the right answer after a few guesses from each member, then the object is forfeit and the OP must post something new or pick the user who had the best guess.
If you are posting something like a video (or anything else for that matter), make sure it doesn't have the answer in the title or URL.

I'll start with some lyrics, name the song and the next question is yours. Name the song and post all its lyrics for credit.
I've got an unfortunate feelin'
I've been beaten down
I feel I don't believe
And now the truth is coming out
What they've taken is more than a vow
They've taken your innocence
And then they throw them on a burning fire
