Mentioned to my kids that Neal Armstrong had died and asked if they knew who he was, and they thought he was the Tour de France cheater. So I straightened them out, and they were all "oh, yeah, we knew that."
And then I saw on Facebook, a friend of mine who works at a university reported that many of his students were confusing Neal Armstrong, Lance Armstrong, and Neil Patrick Harris.
Neil Patrick Harris? WTF! Doogie Howser?
