_cpzh4: Find a good, brief joke in a language other than your mother tongue; if you don;t know any other languages this might be a good way to start learning.

Record your voice telling the joke focusing on pronunciation and try to make it sound as natural as you can with appropriate vocal inflections.

Add a (cc) music track underneath (maybe from jamendo.com) and a laugh track (soungle.com is a good source) at the end.
