Haha, that video was great and I agree with Black_Tiger; it couldn't be a joke . I've seen many nerds in my life time of all sorts of varieties and I can say from a professional viewpoint that the dude is the real deal, totally not joking.
I don't know about you, but I'm watching the rest of his videos. I can't wait to here his opinions on various topics.
Dude, I'm doing the same thing. I didn't know he had other videos until you mentioned it (I'm not too YouTube savvy). I loved how he displayed all the items -- quite the balancing act! And try as he might, he couldn't open the Gameboy case, let alone remove the cartridge.
In all fairness to marktuxedo:
1) he opens and ends the video by saying he has a meager "collection"
2) he admits that he "timestamps everything" (one of his quirks)
