Nerdist:

Hold on to your butts and roll for initiative, because this might be the greatest game we’ve ever played. Together with our sister site, Geek & Sundry, we invited the one and only Vin Diesel to come play Dungeons & Dragons with us… and not only did he accept, he may have become our new best friend.

D&D isn’t cool. It’s fun, and I played a lot in high school and college, but it’s not cool. But, if one of your players is Vin Diesel, a giant buff nerd in his own right, D&D gets very cool and even more fun. BTW, the DM in that video is really good. There’s even a 30 minute version of this on Youtube.
