As long as no one gets seriously hurt, it's safe to say that falling is one of the most humorous things that can happen (remember Hipsters On Ice?). It's like a gag that our feet play on us, and one that usually incites a laugh, because we've all been there—toppling over in front of strangers, tripping on the sidewalk, and losing our footing on the subway stairs. That all makes this video an instant classic—watch one man's documentation people tripping up a subway step that's a fraction of an inch higher than all the other steps.
