Without wishing to open myself to the wave of death threats from the US that Charlie Brooker received when he made a similar reference -
Guy Fawkes, where are you when we need you?
(Charlie Brooker signed off with a throwaway gag about George W Bush winning another term in his Guardian column a good few years back, and it got reprinted online out of context, leading to a huge number of badly spelled death threats and hate mail from scary rednecks. It was ?John Wilkes Booth, Lee Harvey Oswald, John Hinckley Jr ? where are you now that we need you?? - He went on to say that he's never had any problems with a single 'real' american, and loves the country, but online people are dicks.)
You've gotta think tho, a few hundred barrels of gunpowder under both Congess in the US, and the House of Lords in the UK, and of course it would be a tragic loss of life, but they'd suddenly need to replace them all with younger, alive people who have maybe even heard of things like the wheel, fire, and the internet.
*Awaits my extradition to the US as a probable terrorist*
I've seen two and a half men, I know for a fact much of the US doesn't get humour
