"Thank God, It's Doomsday" is the nineteenth episode of the sixteenth season of the American animated television series The Simpsons.

Executive producer Al Jean claims that the commentary recording session for this episode was the last time he saw Payne.

Despite being consoled by Marge and Lisa, who think God would not end the world unless He announced it, Homer encounters signs suggestive of the Rapture.

Homer later wakes up on the mesa and is reunited with his family and discovers Moe's Tavern to curiously be back in its normal set up.

[2] Execute producer Al Jean claimed that the final time he saw writer Don Payne before his death was for the recording of the DVD commentary for this episode.

In the final scene, Homer, his fellow bar patrons, and Moe form a tableau of the painting The Last Supper by Leonardo da Vinci.

[8] Walter J. Keegan, Jr. of TV Squad said the "storylines are getting thin" to be writing an episode parodying the Left Behind franchise.

[4] Colin Jacobson of DVD Movie Guide said the series does not "tend to handle religious subjects very well" and felt the episode lacked direction and jokes.
