When John Titor first showed up on IRC chat in October of 2000, he was enjoying a neat kind of double billing - as his 38-year-old self sat downstairs in the kitchen, typing away, a two-year-old version of himself lay sound asleep upstairs in bed. The elder Titor had been sent back in time by the U.S. Army, which needed him to fetch some legacy computer hardware from the 1970's, and he had a sort of layover in the year 2000. So like anyone with time to kill, he went online.
