Alright people, here's the facts on lighting farts.
Not everyone has methane in their farts, but I think 1 in 4 or 1 in 5 people DO. If you're one of these lucky people you can light your farts. I worked with a guy who could do this. He would keep his pants on, sit in a chair and lift his legs up as high as he could so his ass was sitting out as he was sitting there, then he'd light his lighter and hold it near his pants and let them rip. One of them almost burned his face because the flame was so big! I think depending on what he ate it would vary the size of the flames. I think he drank a lot of beer and stuff. I think once his pants kinda caught on fire a little, but he just patted it out. I wouldn't try it bare assed, especially if you have ass hair because it won't be there for long if you light one.
So yes, some people can light their farts!
