It is all a bit of harmless fun, although to see your own effigy burned on the fire most be quite unsettling.
I have very found memories of being a child in the U.K. standing with my family, chanting Guy Fawkes rhymes and watching the fires burn.
"Remember, remember, the Fifth of November! the Gunpowder Treason and Plot.
I see no reason why The Gunpowder Treason should ever be forgot..."
"Rumour, rumour, pump and derry! Prick his heart and burn his body,
And send his soul to Purgatory."
Enjoy your Guy Fawkes Cocktail.
