This is a video (including some stunning shots through the glass roof) of the world record for most playing cards being toppled like dominos, with a very impressive 51,725 slightly bent cards getting knocked over. Damn, and I thought standing dominos was nerve-racking, this must take a REALLY special kind of person. Which I am not, just to be clear. I am very average. Well, except in the…you know. “Idiot department.” Exactly.
