Rex Huppke is  a humble guy, but I like to think of him as a national treasure. His writing manages to make important subjects palatable to wide audiences, and also somehow makes serious topics funny. His articles are smart, clever, and witty.  His satirical obituary for facts was named one of Time Magazine’s Top Ten Opinion Pieces of 2012, and became a viral hit.  My interview explores how he handles feedback from readers, how he went from engineer to writer, and what it was like to be in the room when the Oklahoma City bomber, Timothy McVeigh, was executed.
