In the movie Tremors III: Back to Perfection, there is a character in the movie that is obsessed with weaponry, explosives, and everything that goes "BOOM". There is a scene where they are running from these things they call "Ass Blasters" and they run into a porta-potty if you would like to call it that. Well, he says.... If we stay in here long enough the gasses in here will combust due to our body heat in just a few minutes. Or something reletive to that. What I would like to know is if heat from your body could actually make to fumes from a porta potty ignite whether it be in a few minutes or maybe a few hours. I think this would be a pretty cool myth. But, if you would put it on the show I would really appreciate if you would say something along the lines of "We recieved this myth from Intrepped (In-trep-id) from the state of Pennsylvania". Thank you.
