Uh.... you're going to have to go back a little farther than Y2K. Y2K was NOT a "hoax"... it was an event that would have been extremely serious if not for a great deal of effort on the part of a BUNCH of people.... myself included.
I spent two years finding and fixing problems... then, enjoyed champagne on New Years Day!
Maybe... the Greatest Hoax since... hmnn... well.. EVER!
Ditto that!
