Today would have been Mark Twain's 176th birthday. Instead of celebrating this annual occasion by cracking open a copy of The Celebrated Jumping Frog of Calaveras County or watching Jonathan Taylor Thomas and the late Brad Renfro in 1995's Tom and Huck, PAPERMAG decided to mark this special day by compiling the 14 most upsetting photographs of Mark Twain impersonators -- one of the weirdest lookalike genres behind Elvis and Sarah Palin -- we could find. So grab your laptop and hop on your raft, because it's time to take an odyssey with a bunch of white-haired weirdos.
