For those who don't know, Guy Fawkes was an Englishman who misbehaved badly centuries ago. It's a sort of holiday over there, especially among those disinclined to behave all that properly today.
Hangings, disembowelment while still conscious, and dismemberment (quartering) with the dismembered parts dipped in hot oil and put on display at each major entrance to the city.
But Guy Fawkes beat the sentence... as he climbed up ladder on the gallows to be hung without being killed (so the above could be done to him), he jumped and broke his neck so that he wasn't conscious while the above was done to him....
