So lately I've been seeing these billboards that say that Armageddon will be on May 21st. I looked this up, because I have never seen a certain date being so frequently used. I heard this clip of a guy giving bible references and mathematically giving the date May 21 2011. (I didn't have the patience to listen to the whole thing so don't ask me how he got this) And I immediately thought of this Simpsons episode: http://en.wikipedia.org/wiki/Thank_God,_It%27s_Doomsday
