HBO's Last Week Tonight with John Oliver made its own attempt at a doomsday video, with narration help from actor Martin Sheen.

The aim was to produce a better doomsday video than Ted Turner did for CNN in the early 1980s. That video was intended to be the network's last broadcast in the event the world was ending. In Turner's vision, the last thing anyone would see or hear as the world was engulfed in flames was The Army Ground Forces Band performing the old hymn Nearer, My God, to Thee -- the song allegedly played as the RMS Titanic was sinking.

"This cannot be the last thing we all see," Oliver said, pointing to a screenshot of Turner's "dull" video. Going for a "happier" tone, the host introduced his own tongue-in-cheek version. Enter Martin Sheen, who intoned:

I'm afraid if you're watching this, the end times are upon us. Whether because of war, disease, or a genetically modified dinosaur, our world is now only moments away from total annihilation. So, let's take these last few moments to celebrate the greatest things about humanity's time on Earth. We had a good run, didn't we?

Over scenes of man's first fire, the invention of language, and even the Segway, Sheen journeys through man's accomplishments -- even his "total domination of every other species" as a room full of prized trophies hang on a hunter's wall.

"Nice try, lions," Sheen remarks.

Then there is the "blooper reel" -- groin shots, Nazi Germany, the atomic bomb -- followed by a "thank you" segment for peanut butter, water slides, The Beatles, and "that YouTube video of Kelsey Grammar falling off a stage."

"So, now before we are all vaporized, or whatever awaits us," Sheen concludes, "I think it's fitting that the last thing we all see is this sick basketball shot." (A young man is shown doing several acrobatic maneuvers with a basketball and nailing a long shot.) 

"We did it! This is Martin Sheen. Over and out."
