World of Warcraft Easter Egg - O Rly?

Given the release of Patch 1.9, a few new characters have appeared in Azeroth following a recent internet fad:

1. A Booty Bay auctioneer sports the name "O'reely"
2. An Undercity auctioneer sports the name "Yarly"
3. A small pet owl that has appeared near a tent in the far northeastern corner of Silithus is named "O'reily"
