Is This The Worst British Accent You Have Ever Heard

I'm just going to leave that video up there for you to watch. You'll either love it or you'll cringe. The fact is that I can do a few voices and accents. The problem is that I always seem to do the wrong one. If you ask for a pirate voice I'll give you a leprechaun. If you ask me to sound like Elmo I'll probably sound like a viking.

We were discussing the signing of Magna Carta and I tried to sound pompous and British. Does that make me bad at voices or just bad at timing?
