This guys favorite book must be something called like "THE BIG MOTHERF*CKING BOOK OF IDEAS", written by a standup comedian-turned-NYT-writer, where the thesis is somewhere between "Space is so. fucking. big." and "Guess what? Nothing matters so get back in your cubicle". You can find it on a bargain shelf at Goodwill or on the bathroom counter of your second-drunkest uncle.
