My uncle Jack's off

A very funny "childrens" book written by Bo nehr, that includes multiple references to "Veiny Necked Birds", "Big Hairy Sacks", and "White Sticky Trails". The title of the book can be misleading to some, so to clarify, the apostrophe between the K and the S is replacing the letter I, so the title of the book is actually "My Uncle Jack IS Off", for all you dirty minded schlongs out there
