This weeks’ new episode of The Big Bang Theory features a special guest star portraying himself, something this sitcom does especially inventively from time to time (Stephen Hawking! Leonard Nimoy!). Tonight’s guest is author and graphic novelist (Stardust, The Sandman), who shows up at Stuart’s comic book store and gives it a very influential seal of approval. Scribes at Minnesota’s Star Tribune note that Gaiman, years ago, did the same thing to Minneapolis’ DreamHaven Books & Comics, helping to make that store famous by his patronage.
