If a man does impressions in the forest and no one is there to hear him, does he sound like someone else? Yes, so long as as he is records and uploads it to YouTube.

Jamie Costa is an impressionist whose spot-on impressions include the likes of Robin Williams, President George W. Bush, Matthew McConaughey and Gandalf. His collective work is so strong he can be forgiven for failing to use landscape mode. Let's just hope he isn't attacked by a bear on his way home.

Be sure to check out the rest of his impressions on his YouTube channel (and thanks to Reddit for the find)!
