Museum of Humor.com is a gold mine of fine funnies, especially for people who are called upon to give presentations -- live or online. The site divides humor into categories -- quotes, anecdotes, definitions, one-liners, and so on -- and offers hundreds of links to each kind. A large list of links to offbeat news items offers additional amusing material that applies to a wide variety of subjects.

The Museum of Humor.com also has indispensable writing tools such as rhyme generators, simile generators, cliché lists, phrase finders, "Today in History," Guinness World Records, and new-word generators. And if you have to use statistics in a presentation, check out "Calculated Humor" in the Exhibits section of the museum. It provides tools for making statistics less boring and more entertaining. (Just to see the Penguin-o-matic Convertor is worth the visit. It converts weights and distances into numbers of penguins.)
