The internet is rife with memes featuring old people, but some grandpas are just way more awesome than others.

Old people have slow reflexes and are pretty confused by technology, on the whole. Though it can be kind of infuriating to try and explain what a "tweeter" and "the face book" is to someone who was raised before television, it's also pretty funny to watch them get overwhelmed/excited about tech stuff.

So what happens when you introduce your 84-year old grandfather to 'Black Ops 2' and 'Halo 4' for the first time? Hilarity and awesomeness, apparently. Does this work on cranky nanas?
