It's finally here: Comic-Con 2009! Whether you're reading this from the comfort of your living room in the Midwest, or the comfort of a hard sidewalk as you wait in line for the NEW MOON panel, your heart has to be racing for all the fun in store these next few days. Screen Junkies will be there the entire time, quick on the draw with our Twitter, and posting updates right here on the site. To kick off the convention, we thought we'd offer a word to the wise attendee. In the below video clip, Kevin Smith shows us why you never heckle a man with a microphone. His voice projects a lot louder than yours, and that includes when he makes fun of your mother. So remember fans, well thought out inquires only. Note: If you have trouble viewing the video click here.
