The notes featured in the book are mostly funny, but other things detracted from the enjoyment. Some of the handwriting is hard to read. Occasionally there are minor obstructive differences between British and American English. But the thing that virtually suffocates the book's humor is the author's commentary which appears beside each note (doubling the pages). They have all the effect of dissecting a good joke to find out why it's funny -- when done, nothing funny remains. They are as fun as getting drunk with a grammarian.
This would be a good gift for former roommates or those currently suffering by such hands. If you want a rich compilation of notes and the like that demonstrate the comedy and tragedy of our discarded thoughts, try Davy Rothbart's Found series. For something specific to roommates, try College Humor's "Roommate Confessions."
