As to original topic, is he a mark? Yes, but fucking have fun with it. I LOVE using my knowledge to "predict" what will happen next in front of marks and having them worship me as the all knowing one. Also, most marks for some reason think SmackDown is live, so when I can literally tell them EXACTLY how every match and segment ends, they think I am a wrestling God...and not in the JBL sort of way.
Just have fun with them, and realise that it is cool and to some extent envious that they still love every good guy and hate the bad ones, I mean some of my favorite times as a fan wasn't when I enjoyed good matches and cared about storylines, it was when I cheered the faces and boed the heels simply because of their character. My friend Mark (literally his name) knows all the ins and outs of the business. Hell he trained to be a pro wrestler with me, and somehow he still is so markish it's funny. As soon as someon turns heel he can't remember why on earth he ever liked them. Case and point, he thought Lita was the greatest Diva ever and was the hottest thing on earth, didn't give a shit about the Matt Hardy triangle, but as soon as she turned on Kane he hated that ugly bitch so damn much. It's really kind of funny and enjoyable.
