Back in the days of "America's Funniest Home Videos" people across the country would relax after a long workday by watching strangers fall on butts, fail at PDA, and generally humiliate themselves. The popularity of that show proves not only the public's enduring love of slapstick, but also just how much we all love watching each other fail.
While this love of public failure can be construed as cruelty, it's a natural side effect of the fact that we all fail and humiliate ourselves regularly, in small ways and large. So, seeing others in the same boat is both comforting and entertaining.
If you're in need of a reminder that your awkwardness and failure is far from singular, then these posts of people struggling will serve you well.
