Once I stumbled upon this bit of whimy, I had to play with the search engine a bit. I found 7 people have listed Harper Lee's challenged Boo Radley, from To Kill a Mockingbird, although the existence of a rock band by that name may skew the results. One of our dogs is named Scout, for a reason. Interestingly, something like 17 listed Eleanor Rigby on their interests list.
I'd put some pithy close to this, but I want to see how many people put "comfortably numb" among their interests.
