I really enjoyed Jon Stewart's previous book, America (the Book), so I was looking forward to reading this one - a guide to aliens about our world. Of course, America lent itself more readily to Stewart's political humor - while this one takes on a far wider scope. With chapters ranging from religion to science to culture, I found that it was pretty hit or miss. There were definitely some laugh out loud lines and clever turns of phrases (particularly in the religion section), in general, I felt like this book was trying too hard. Definitely an entertaining coffee-table read to pick up now and again and leaf through, but as a book to sit down and read from cover to cover, I found it a bit underwhelming.
