The past few weeks, Conan has been presenting video evidence that Alex Trebek has been hosting Jeopardy! for too long and has accordingly gone completely insane.  This “evidence” consists of spliced clips of various Jeopardy! clues made to seem like one nonsensical clue (e.g., “This ugly guy, Will Smith [not the black one] can sometimes track down one of these Irish fairies, in this type of marriage”).  Think of it as Jeopardy! Mad Libs.  And Jeopardy! Mad Libs works so well in large part due to the voice of Alex Trebek, one of the best enunciators in North America.
