It's a word of mouth folk genre that begs to be cataloged and presented for our amusement. Luckily, quite a few brave souls have taken on the challenge of preserving our best and worst humor via the World Wide Web. The results range from joke lists that will be inaccessible tomorrow to well-organized joke encyclopedias that wouldn't fit anywhere but on the Net. Humor is quite a broad category, so web sites tend to specialize at least a little. There are sites for deaf jokes, lawyer jokes, redneck jokes, and jokes over fifty years old.
Some sites focus on practical jokes and pranks.
Some are discriminating about their content, whereas others will let anything with a punch line on their pages. Humor appeals to all mentalities and dispositions, and the Web provides resources for anyone who has ever smiled in their life. In this age of political correctness, the appropriateness of some jokes can be questioned. For those who are worried that their sensitive nature will be offended, or that innocents will be slandered, many sites offer some sort of rating or screening system. They flag risqu jokes, or rate them like the movies, or let you filter out anything aimed at your favorite ethnic group.
