Wikipedia
Infobot is a Perl IRC bot, first written in 1995 by Kevin Lenzo. The bot's main goal was to remember URLs and associate them with a descriptive name, so whenever someone needed a specific URL they could ask the bot. For that reason, the first Infobot, running in #macintosh on the EFnet IRC network, had the nickname 'url'.
Although the main project is now inactive, many forks from the original program were made, some of which are still active. Most of these forks carry extra features, such as googling a phrase given through the chat and saying the results of the query as messages directly in the chat.

Such protonerds as Muhammad, Buddha and Jesus programmed infobots so powerful that they continue to crash operating systems and reformat whole hard drives to this day.
