Miss Piggy is probably polishing her right hook — the ”humanoids only” rule kiboshed a listing for her Royal Pigness — but almost every other fictive 20th-century pop-culture figure makes an appearance in The Encyclopedia of Fictional People: The Most Important Characters of the 20th Century, a collection of the most famous biographies never written. Well, at least those who hit it big before 1994. The Friends crew (mercifully) are absent, but you will find everyone else from Holly Golightly and Uncle Fester (betcha didn’t know his last name was Frump) to Nathan Detroit and Pippi Longstocking. Even Popeye and the Simpsons get face time. (Yes, they have Dr. Doug Ross and Mulder and Scully, too.) There are mistakes: MacGyver is listed in the ”Gadget Junkies” sidebar but has no encyclopedia entry, and Mrs. Doubtfire’s first name is Euphegenia, not Edwina. But for a quick nostalgia fix or as a Jeopardy! primer, Fictional People serves up some wonderfully arcane fare.
