Collections of jokes are listed online at Unijokes.com, ManWalksIntoAJoke.com, and JokesGallery.com. Visitors can browse jokes and vote on whether they are funny. These websites use different methods to collect votes: plus and minus buttons, a one- to five-star rating system, and a grading structure with scores between one and 10.
Jokes are listed by category. Example categories are marriage, school and money. Categories differ between sites, and some categories may be offensive to some viewers. The number of votes for each joke is shown alongside the overall score given by a collective online audience for how funny or not funny a joke is deemed to be.
