In an interview on NPR, Borowitz talked about The 50 Funniest American Writers as a bathroom book. I don't know about bathroom, but it is probably a book you want to dip into from time to time and read an essay here, a story there. Reading it all at once tends to get you jaded. You begin to suffer from the law of diminishing returns, and suddenly things aren't quite that funny. You may not want to keep the book in your bathroom, but you might well want to keep it handy and read a piece or two to take a break from War and Peace.
"A sinister cabal of superior writers."
