Lest we forget, there was only a few years ago much speculation that Neal Pollack was merely a front man for Dave Eggers; that Neal's now-forgotten and not very good first book (I can't recall the title) was actually written by "The Dave."
The thinking at the time was this: People saw Neal, a buffoonish clown shouting at train stations, scarcely more advanced than Benji the Idiot, and couldn't believe that he was even capable of scrawling his name. (This is how he presents himself to people to this very day.) Ergo, someone else did his writing. Who else but his mentor and patron, Earl of Valencia, Duke of McSweeney's?
