One day isn't enough. Three new books cover different varieties of foolishness.
College in a Nutskull: A Crashed Course in Higher Education (Workman), compiled by Anders Henriksson, is a professor's collection of real — and really alarming — student "knowledge," like this gem: "In his play Cliff Notes, George Barnard Shaw illuminates social issues that would not be so easily exploded in other medians."
Little Billy's Letters: An Incorrigible Inner Child's Correspondence With the Famous, Infamous and Just Plain Bewildered (William Morrow) by Bill Geerhart compiles prank childlike letters to politicians, entertainers and others, plus their sometimes hilarious responses: The CEO of Starbucks advises Billy on what college courses he should take if he wants to grow up to be a barrista.
Undateable: 311 Things Guys Do That Guarantee They Won't Be Dating or Having Sex (Villard) is advice for the lonesome and/or clueless on the turnoff factor of mullets, facelifts, cell phone holsters, cute names for body parts, undertipping, painting your face for sporting events and more.
