Remember that mysterious sidewalk lane separating tourists from New Yorkers that quickly became "the talk of the Internet" last month? After intense speculation about who was behind the gag, the pranksters have finally revealed themselves: It was Improv Everywhere, of course. This funny video shows them posing as DOT workers installing the "pilot" project, then enforcing the tourist/New Yorker separation, and even soliciting public comment from pedestrians about the project.

Our favorite part is probably when one tourist tries to convince the DOT enforcers that he's fast enough for the New Yorker lane, and they tell him, "Nope, doesn't matter. Statistically you walk slow." Also, isn't it great how easily everybody just submits to the new rules, no questions asked? If you put on a reflective work vest and bark orders, you can get people to do anything.
