1.  Paul Shaffer as George Costanza? According to Shaffer’s memoir, We’ll Be Here for the Rest of Our Lives, Jerry Seinfeld personally left a message stating that the role of George Costanza on his upcoming pilot was Shaffer’s if he wanted it. But Shaffer was preoccupied with his other work and said he never got around to returning Seinfeld’s call.

  2. Seinfeld plot: A New York Public Library investigations officer named Mr. Bookman comes after Jerry to track down a copy of the Tropic of Cancer that Jerry took out in 1971 and never returned. At the cost of a nickel a day for 20 years, Kramer surmises, such a long-term offense will cost Jerry $50,000. After conducting his own investigation, Jerry finds that it was the Tropic of Capricorn he returned so many years ago, not the missing Tropic of Cancer. He relents and writes a check (for much less than $50,000) to the library.

    Real-life story: On Feb. 4, a branch of the New York Public Library received a long-lost copy ofThe Fire of Francis Xavier, 55 years after it was first checked out. While the real-life literary fugitive wasn’t apprehended by the dedicated efforts of a humorless library cop, he or she clearly felt some shame, opting to send the book through the mail instead of dropping it off in person.
