About this "The Simpsons" episode:

The Simpsons - Thank God, It's Doomsday is the 19th episode of season 16 and number 354 overall in the series.

The title of the episode is a reference to the popular saying, Thank God It's Friday.

Homer sees a movie about the end of the world and fears the same thing will happen in real life after seeing a chain of random occurrences (celebrities ["stars"] falling from the sky, raining blood, a man in a realistic devil costume) and doing a complicated math equation that predicts the end will come on May 18th, but when the end does not come, Homer discovers a flaw in the equation and ends up in Heaven where he meets God and learns that God is planning The Rapture.
