May the source be with you, but remember the KISS principle ;-)
Bigger doesn't imply better. Bigger often is a sign of obesity, of lost control, of overcomplexity, of cancerous cells
Version 1.01, October 30, 1992
Written by Jeff Okamoto
With Help from Tom Christiansen
This is similar to other Purity Tests, of which perhaps the most famous is the Unisex, Omnisexual Purity Test that can be found in soc.singles. Additions are welcome. Please send them to firstname.lastname@example.org
All questions begin with "Have you ever..." Answer each question with a "yes" or "no". Keep track of how many "yes" answers you give. When finished, subtract that number from the total number of questions, then divide by the number of questions to get a percentage. This percentage is your perl purity. There are 125 questions in this version.
