The Impressionists

I like David Letterman. I'm not quite sure what the parallel is. Although he's got a kind of, he's a bit cheeky, isn't he? With the way he treats people. You wouldn't recognise your own voice if you heard it particularly because I don't know what happens to sound waves and things,. but it doesn't sound like what I hear. That would be a sad lie. Are you an impressionist yourself? Kevin Spacey famously just reels them off when you're talking to him. Benedict Cumberbatch and Tom Hiddleston have a rivalry. Who do you think is the best?
