Does The Laugh Factory welcomes new, unheard-of comedians? For example, could someone like myself, who wants to be a stand-up comedian, go to there at a certain time on a certain day and get four or five minutes on stage to show what I got?

Yes! Open mic is usually on Wednesdays I believe. You can check the website.
