There are many types of joke books in print today; a search on the internet provides a plethora of titles available for purchase. They can be read alone for solitary entertainment, or used to stock up on new jokes to entertain friends. Some people try to find a deeper meaning in jokes, as in "Plato and a Platypus Walk into a Bar... Understanding Philosophy Through Jokes". However a deeper meaning is not necessary to appreciate their inherent entertainment value. Magazines frequently use jokes and cartoons as filler for the printed page. "Reader's Digest" closes out many articles with an (unrelated) joke at the bottom of the article. "The New Yorker" was first published in 1925 with the stated goal of being a "sophisticated humour magazine" and is still known for its cartoons.
