A woman wearing jeans and a crewneck t-shirt walked around NYC for ten hours with a hidden (to everyone else) camera fixed on her. Below is the result, which features a greatest hits of catcalls, like: "Smile!" and "Hey baby!" Also featured is the most infuriating catcall of all: "Somebody's acknowledging you for being beautiful—you should say thank you!" Ladies whenever will we learn to smile and thank our street harassers?

On the non-verbal side, there's a cameo by the creepy lingerer who decides to walk right next to you forever like you're on you're on a goddamn first date or something.

Take a walk in one woman's all women's shoes:

The PSA, highlighting the impact of street harassment, was put together by Rob Bliss and Hollaback—they explain that the woman, Shoshana B. Roberts, "volunteered to be the subject... For 10 hours, Rob walked in front of Shoshana with a camera in his backpack, while Shoshana walked silently with two mics in her hands."

Bliss says he wanted to create this "because I think a lot of men don't understand the collective weight that this harassment causes. They see it as just an innocent 'compliment' but are missing the forest for the trees."
