When you see it, and when you see the other it.

Neat, it's a real book

"For the Experience"

"I Love Dick" is a pretty well-known book. https://en.wikipedia.org/wiki/I_Love_Dick

Is the 'other it' the book on the left saying 'The once and future sex' or the 'Staff Dicks' sign on top?

"New Releases & Staff Dicks"

"Excuse me, I can't seem to find any of the staff dicks. There's just a bunch of books on the shelf where the dicks should be."

Staff Dicks: "I love Dick"

The Once and Future Sex

Huh, that section is usually in a separate room.
