My favourtie y2k joke:

A COBOL programmer was sick of working on year 2000 problems. So he had himself frozen to be woken up in the year 2001. When he awoke everything had completely changed. "What happened?" he asked.
"There was a glitch in the software. You weren't unfrozen in 2001. In fact, we're coming up to the year 10,000 and we understand that you know COBOL..."
