This novel is not to be tossed lightly aside, but to be hurled with great force

This is an insult, but I found it to be funny, so I am including it here. It has been attributed to a lot of different people, but I don't think that anyone really knows who first said it.

The critical element of the joke is the deconstruction of the colloquial phrase "toss aside", which means to discard or ignore something after brief consideration. When it is usually said that something should not be tossed aside, the person is saying that the thing is better than it first appears.

This statement circumvents the normal use, and replaces it with the idea that the book should be not just lightly tossed aside, but actively (and forcefully) tossed aside. This book is really really bad (and probably worse than it may first appear).
