My roommate plays neverwinter Nights - a Dungeons and Dragons computer game hosted on a public server. He's a DM, and one of his other DMs gave his 30th level sorcerer - Who had around 250,000 XP - 2.7 Billion with a B XP.... And suddenly, the game claimed he had negative 2 Billion XP. Whoops.
Aha. I knew exactly what happened.
