Happy Guy Fawkes Day

Apparently, some disgruntled Catholics decided to blow up the Protestant King andParliment in England in 1605, but were stopped at the last minute. To this day, England, New Zealand, and who knows what other backwater regions, still commemorate this event. What puzzles me is that even though the assasins are supposed to be the bad guys in this story, they named the holiday after one (Guy Fawkes) and they celebrate with explosives (fireworks). It would be like calling July 4th "King George III Day" and eating bread pudding. Crazy Limeys!
