It was like magic. Somewhere in Heath Ledger's wonderful performance, the worst people you knew heard a dog whistle. A dog whistle which screeched "Annoy the f**k out of everyone you know and love." The Office understood that this was going to happen, and that's why "Employee Transfer" is so great.
Airing on October 30th, it was like a warning to the general public: Beware, for tomorrow your neighbors will turn on you, your children will betray you, and your roommates will spend six hours attempting to apply cheek prosthetics before giving up and just using a pound of lipstick. Any show that can accurately capture the frustration of existing in the same universe as the mob of Jokers before that day of frustration actually occurs is worth your attention.
"Employee Transfer" features some of Steve Carell's best acting in the whole series, but it's also a great parody of the time the Earth cancelled Halloween and replaced it with Jokerfest 2008. I'll never forgive Christopher Nolan. Never.
