Because public transport is an utterly mundane space, people-watching is a popular sport on trains and the like—a known fact that The Chortle banked on with their video "Taking Fake Book Covers on the Subway." The video does just as it promises: a dude takes fake book covers on the subway. The titles he "reads" are much more uncomfortable for public consumption than 50 Shades of Grey.
OK, someone must've come up to him and asked when Gone Girl 2: Even Goner comes out. Aside from that title, all the others were attention-grabbing in the worst way possible. It's a bit surprising no one came up to him and started screaming in his face—dude's on the subway in New York, after all.
