Simply. Awesome.

That's what I said to myself when I watched Blizzard's Diablo III and Starcraft 2 April Fools Jokes. They have a history of doing a great job, but IMO they have really pushed the boat out with these two offerings:

1) Diablo 3's new Character Class: The Archivist.

2) Starcraft 2's new Terran uber-vehicle: Terra-tron.

Watch the two associated shorts. As I said, awesome.

Kudos Blizz. I wasn't impressed with 'P1mp My Mount', but the other two more than make up for it.
