Some of the dumbest things we've seen people do can also be the funniest. The TV show, World's Dumbest depicts just that. No doubt we can look back at our lives and remember some really dumb things we've done. Some of them made for good laughs while others had some major repercussions. Dumb, stupid, and foolish can come so naturally to us if we're not careful. Maybe it's time we exchange dumb for some wisdom.
