From an interview with Stephen Colbert in GQ in 2015:
He smiled in anticipation of the callback: “ ‘You gotta learn to love the bomb,’ ” he said. “Boy, did I have a bomb when I was 10. That was quite an explosion. And I learned to love it. So that’s why. Maybe, I don’t know. That might be why you don’t see me as someone angry and working out my demons onstage. It’s that I love the thing that I most wish had not happened.”
I’m still waiting, Colbert. This thing I most wish had not happened. I’m 31, not 35, but my mother is dead, and it has been eight years since she was diagnosed with forgetting all of us. Five since cancer took so much more of her away so fast. And it still sucks, man. She’s dead, and it still fucking sucks.
