For obvious reasons, I've had the following running through my head all day:

Remember remember the 5th of November,
The Gunpowder, Treason and Plot,
I know of no reason why the gunpowder treason
should ever be forgot.

I knew a bit of the rhyme before V for Vendetta, and now I can't hear it in my head without Hugo Weaving's singsong baritone rumbling it through. What I now know, courtesy of Wikipedia, is the rest of the rhyme...

Remember remember the 5th of November,
The Gunpowder, Treason and Plot,
I know of no reason why the gunpowder treason
should ever be forgot.

Guy Fawkes, Guy Fawkes, 'twas his intent
to blow up the King and the Parliament.
Three score barrels of powder below,
Poor old England to overthrow:
By God's providence he was catch'd
With a dark lantern and burning match.

Holloa boys, holloa boys, make the bells ring.
Holloa boys, holloa boys, God save the King!
Hip hip hoorah!

A penny loaf to feed the Pope.
A farthing o' cheese to choke him.
A pint of beer to rinse it down.
A faggot of sticks to burn him.
Burn him in a tub of tar.
Burn him like a blazing star.
Burn his body from his head.
Then we'll say ol' Pope is dead.

Hip hip hoorah!
Hip hip hoorah!

My old friends in England will be having fun tonight. :)
