My favorite is when Intel demoed the new ivybridge iGPU by having a guy fire up VLC player to play some footage of a racing game while he pretended to control it with a steering wheel controller.

I looked this up and it's actually even worse than than I thought. When called out he claimed it was being control from backstage.

I was curious and went looking for it. That's pretty hilarious oversight!
