I was in class, a life skills class in high school, one of those "don't do drugs and be yourself" classes. That is mandatory.
So, they showed us a video where a (I hope) made-up kid used his dad's credit cards to buy WoW (cleverly disguised as "Worlds of Warfare", thanks, lawyers) gold and weapons and it got stolen or something and the kid was confused. The kid was clearly dropped on his head or something, but that's not the point. The teacher then inquired as to whether "Worlds of Warfare" was a real thing, and someone in my class said that it was probably just World of Warcraft in disguise. My teacher then asked if anyone had actually played it, and I foolishly raised my hand, the only one in the room of about 25 teenagers.
Unfortunately, the nerd inside got the better of me, and I spent the remainder of the lesson (an impressive 20 minutes) talking in what I would call too much detail about World of Warcraft and it's various nuances. I discussed the currency, the auction house, player groups, guilds, you name it. At least, I tried to over the laughter.
