YES! An American faking a British accent is genius!I offer for your consideration "British Ponies"
I think what is needed though is an American FAKING a British accent, just slightly off - and occasionally forgetting when angry.
By contrast though, we will have a genuine Ojou-Sama and even the Emperial Family later on, who should be dubbed in more reliably upper class British. It's a shame Penelope Keith is no longer with us....
