According to this article, your grandma is just waiting to punk you playing video games. And by punk, I mean beat the living snot out of you in Madden and Halo.

This makes more than perfect sense, since somebody had to be playing all that Pong, Pac-Man, and Space Invaders over 30 years ago. Why would they stop playing just because there grandchildren with bad hair cuts think they are the kings of the online arena?

Sometimes, a blue-haired ass-whupin' is in order.
