Look at it this way, if you weren't fortunate enough to get your "I survived the Y2K bug" t-shirt (like I did), then a "I survived the apocalypse" t-shirt is like the next best thing.
Man... Y2K bug, now THAT was something, kids.
Every computer in the entire world just...
... kept on running. Business as usual. But we were scared, man.
We. were. scared.
Well, I was.
Got a cool t-shirt for the win, though!
