In what might be his Colbertiest segment yet, Stephen Colbert brought Ken Burns on to his show this week to reveal a surprising fact: His real name is Bobby Roberts; they only call him “Ken Burns” because he’s great at totally destroying guys named Ken with vicious insults. Ken Jennings? Roasted. Ken Griffey Jr.? Toast. Evel Ken-ievel? Bit of a borderline case, but better Google “list of burn centers that only play ’Ashokan Farewell’” just to be safe.
