Since this is the only current Mystery thread that hasn't been closed I'll make this comment here.  Please excuse me Eck for the trespass.  
I feel a little bad because I reported a recent "troll surfacing" as a bad post.  Probably by coincidence or due to similar reports from others, soon a couple of threads were closed and the persona, "It's a Mystery", disappeared (banned?).  
The particular thing that steered me toward this line of thought was a brief PM exchange with "It's a Mystery", that led me to believe he's not the trolling pre-teen I had assumed.  We did some good natured sparring re quotes from a classic Beatles album that left me with this different impression.  Anybody who knows the Seargent Pepper album can't be all bad.
"It's a Mystery", hope to talk to you again, whatever your name.
