Pandora Directive easter egg

Two years ago, someone at the Big Finish Games forum discovered a previously unknown easter egg in "The Pandora Directive" in which the famous infomercial line "I have fawllen and I can't get up!" can be heard if you click the mouse in a certain way in the Mayan fireball room. Maybe over here at UTM you guys haven't heard of it yet. Here it is. Follow the link to the BFG thread and you will also see the video clip.
