Grandpas used to be seen as grumpy old curmudgeons who love nothing more than sitting in front of the television shaking their fists at the screen while yelling "damn kids these days!".
But these days we know better than to prejudge someone just because they're a grandparent, and as the populace gets older the grandparents of the world keep getting younger in both attitude and appearance.
Which is why you young whippersnappers out there shouldn't challenge a grandpa to a break dancing battle unless you want to get your electric boogaloo-happy butt handed to you in front of a crowd.
