This morning, Chicago resident Olivia Cole took the Orange Line on her way to work when she witnessed another woman getting harassed on the train.
The 27-year-old saw a guy persistently asking for a woman's phone number.
After the woman who was being harassed stood up for herself, something awesome happened.
Though not everyone picked up on the TLC reference, Cole told BuzzFeed News a handful did and found it amusing.
Cole, who is an author, added that she thought it was a great approach to responding to harassment.
"It was hilarious, and by putting the spotlight on the harasser, he realized how unpleasant unwanted attention can be. They got off the train before I could high-five them, and they deeply deserve a high five."
