I was thinking about taking the programming course at my high school (I didn't know the horrors of Visual Basic at that time). The teacher heard that I knew perl, and asked if I could help out with a script the school had been having trouble with. I thought that sounded like it might be a fun project (I'd never been able to touch production code before), and said I'd come by after school to take a look at the code. I showed up, and the teacher gave me a ten-page printout of this convoluted perl script, and told me that I could just circle any problem I found and write notes in the margin when giving it back...
I decided not to take the programming course.
