Mr. Natural is a 1960s guru, "th' only knower of th' cosmic mysteries alive at this time." Calling him a "mystic madcap" gives the crass, less-than-compassionate charlatan the benefit of the doubt. He is not particularly wise or helpful; in fact, he's a lecherous, grumbling old geezer who gives advice such as "When you arise in the morning, you should do last night's dirty dishes . . . then you should sing a simple melody (of your own choice) . . . then you should call somebody up (not me) . . . then go to the store . . . buy some asparagus." True to the collection's name and R. Crumb's reputation, the stories are sometimes sexually graphic (especially in the scenes with Devil Girl) and a bit on the violent side. Still, there's an innocent, upbeat quality to this comic reflection of America's most notoriously freewheeling decade.
