Granted, now all humanity can say is Wasabi.
Humanity manages to move on by creating another method of communication. However, as expected of humanity, factions emerge on the proper pronunciation of Wasabi; which inevitably leads to a series of wars which devastates the entire world leaving it a blasted, radioactive wasteland. You manage to survive the next 50 years by drinking the milk of pregnant rats deep underground in the sewers.
However, you're found by the remnants of humanity, which is odd considering only 100,000 exist in the entire world compared to the original 6,000,000,000+. They sentence you to relive the memories of the war seen through the eyes of the millions war casualties which were recorded as they waited to die from the horrible pain caused by the advanced weaponry only a never-ending war could have engendered; all beamed directly into your head via medical technology which indirectly keeps you alive. Oh, and they also stimulate the pain center of your brain directly, just because. Isn't technological progress wonderful?
10,000 years after the rest of humanity has died and/or become horrible mutants due to background radiation. The energy source of the machine keeping you alive is finally exhausted, thus you finally die. As you arrive at the Pearly Gates (or one of its analogues), you're asked to state your name. Unfortunately, they only have "Wasabi W. Wasabi" nametags, so they send you down to Hell (or one of its analogues) for an eternity of suffering.
The Devil (or one of his/her analogues) throws you to the masses that were sent down before you for them to do with you as they will. To be free of all that, all you must do is ask for mercy, but seeing as you can't; You remain in that state for all eternity.
And we all lived happily ever after.
I wish for a pair of wool socks.
