methane gas

Does anyone remember hearing any stories about a six hundred pound man asphyxiating himself by his own flatulance? Something like, he couldn’t move from his bed, his favorite foods were cabbage and beans, and he basically filled the room with methane gas? Is it an urban legend or is it true? I heard of news casters trying to keep a straight face as they relayed the story on the nightly news.

According to Snopes (an excellent place to check such things out) it’s an urban legend.
