The 36th Street station in Brooklyn has one tiny flaw that sets it apart from all the other subway stations in the city: One of its stairs "is a fraction of an inch higher" than the rest.

It's this tiny discrepancy that makes all the difference, notes resident Dean Peterson. The filmmaker recently spent some time shooting footage of subway patrons emerging from the station only to realize, a moment too late, than one of the stairs is not like the others.

Schadenfreude aside, someone should really fix that thing before a small inconvenience becomes a big problem.
