Vigor - evil VI!
Here’s another good thing from open source! Vigor is a clone of VI editor, with silliest of features, the paper clip, added on. It comes with training programs too - so it must be a hit with people whining about how closed source programs have lot of vendor and third party training 
Vigor Evildoer Specialist (VES), Vigor Certified Evildoer (VCE), Vigor Certified Evildoer + Internet (VCE + Internet), Vigor Certified Evil Scheme Engineer (VCESE) and Vigor Certified Trainer (VCT) are all different certification levels.
Great humour!
