He's printed a number of eyebrow-raising book covers and taken them on the subway just to see how people would react. While Rogowsky sat reading Slut-Shaming Your Baby or If I Did It: How I Would Have Done 9-11, he secretly recorded the reactions of commuters.
As you had probably guessed, the other passengers simply could not believe these books exist, let alone that someone would read them on the train. The reactions ranged from shocked to amused, with a fair number of subjects pulling out a smartphone so they could snap a photo and share it online.
Of all the fake covers, my favorite would have to be Getting Away with Murder for Dummies.
Do you see one you like?
