This is our pick for the funny book of the holiday season. The cartoons have appeared over many months: a goodly number are familiar, but lose nothing by repetition. Tell your customers that if they know anyone who needs a good laugh (and who doesn't), here is the answer. If they know anyone who hasn't forgotten how to laugh, here's a book to tickle their funnybone. Pick it up -- open anywhere -- and you'll make a sale. Price has a genius for detecting human foibles -- and for making the most of absurdities and distortions. The pictures are your selling point. The diary proves that lines and not words are his medium.
