Kevin Smith is the writer of many great comedies: Clerks, Clerks 2, Chasing Amy, Jay & Silent Bob Strike Back, Mallrats, Dogma, etc. He also played the role of Silent Bob in all of them. That's really funny if you've ever met him. He's not silent at all.
Smith gives the best interviews ever, and he does a lot of Q&A sessions at comic book conventions (I've been to two now). The problem with these is that some people can ask some seriously dumb questions. The great part is how funny his replies to them are. Here's one caught on film.
