British site www.constantcomedy.com does exactly what it says in the URL - streaming comedy videos by both professionals and amateurs in a kind of never ending talent contest.
No need to sign up to view, but if you do, you get to vote off videos you do not like and if enough people agree with you the performer gets the axe and the next funny man or woman takes centre screen.
You can choose the videos you think you will like by category on the left-hand side or just browse through them in the video section.
Again - signing up means you can upload your own funny video for people to watch and vote on.
If you like your laughs stand-up style this is the site for you - and while there are some absolutely tragic performances - it is not hard to find some truly funny people
