Bonfire Night, but yes fireworks, jacket potatoes and hot dogs.
It all conveniently ties in with Pagan tradition as well. Fires would be burned to fuel the Sun as the nights are getting shorter.
The gunpowder plot was timed perfectly.
Fawkes wasn't burned as is popularly believed. He was sentenced to be hung drawn and quartered, but escaped his fate by falling off the scaffolding and breaking his neck.
