Yes..that is the prophecy...
And lo! the great condiment prophet came down out of the Holy Refrigerator bearing 2 glass containers and there were ingredients listed upon them...
And lo! lo! ...again... he proclaimeth "Thou Shalt use these savoury goodies BEFORE date due..."
And he was mocked and chortled at with many a snicker(-doodle)...
And Hell-lo! ...His face grew mighty in both colour and wroth ...
not unlike the candied beet relish in the fridge door on the 3rd shelf..
And O-Hell-lo! ...He then propheciesizsaysed to the mocking un-non-believers proclaimeth-ing "There will come a time of great tribblations not unlike what-eth occurreth-eth on-eth the-eth great Heisenburg Enter(-sur-)prise twixt the Kark and the Spook.... and yet nothing like it at all. Where the Great burning Mayonase Deluge shall Drown the world and all you smarmy snickering un-non-beliebers"
At which point the condiment bearing prophet was promptly carried off by the irate crowd to an unknown fate.
