Did you know that NYC subway conductors have to point at a black-and-white board posted at each subway station every time they arrive to the stop? Apparently this is done to prove they are paying attention. A couple subway riders decided to take advantage of this rule to help brighten the days of a few subway conductors while also conducting a fun experiment.

Yosef Lerner and Rose Sack created signs that said things such as, "Point here if you are dead sexy" and stood below the black-and-white board at various subway stops. The experiment certainly seemed to brighten the days of a number of subway conductors. Check out the video below.
