These are things I've actually seen while browsing Barnes and Noble.
  1. The hipster in plaid buying a Donald Trump book.
  2. The Tom Hardy lookalike buying a Glenn Beck book.
  3. The cute nerd looking at erotica novels, and then purchasing 50 Shades of Grey.
  4. The guy who looks like a cross between Jimmy Fallon and Charlie Day browsing the Sex Ed section, and then discreetly picking up a "how to pick up women" book.
  5. The dude who looks like a linebacker buying a One Direction vinyl.
