In the age of viral videos and social networking, grandma dancing to Tyga's "Rack City" is a sure shot. Watch as this kid mouths the words to the filthy club hit while his g-ma cooks, gyrates, and shakes along in the background. It's a hilarious scene, especially at 35 seconds in, when the dude points to his own grandmother while Tyga raps, "Got your grandma on my dick." Really?
