The most unusual program I have ever made wasn't done in Visual Basic... it was done in Clipper (Uses DB4 files for those who want to know).

It used to take a 2MB text file which was exported from the messages of an Adult Bulletin Board system and looked for keywords. It then collected information about the "women" who posted to those boards and collected information about their physical attributes

Don't ask!! Because I wont tell you what I did it for ;D
