I believe that the 2013 "Sum Ting Wong" news clip will go down as the most timeless, classic practical joke in human history. We'll laugh about it with our grandkids, and they'll do the same with theirs. Future civilizations will study it alongside the Pyramids of Giza, the concertos of Mozart, and the theory of general relativity as being among the most significant of human achievements.
If you don't know what I'm talking about, I feel bad for you, son. But look it up on YouTube and witness some rogue intern's historic feat of misdirection.
