The Daily Grind: What are your favorite emotes?

Emotes add flavor to a game, and frequently add humor, too. Roleplayers especially appreciate them, as they allow characters to communicate other than through text alone. Practically all MMOs use emotes to some extent, and the addition of new ones is often that little extra bit of candy when a patch comes along; for example, Age of Conan will shortly be adding a male version of the female 'sexy dance'. The latest games appear to be taking emotes to new levels. Non-verbal communication is so important in Champions Online that characters will even be able to use facial expressions to convey emotion.

Some games have emotes specific to them that you won't find anywhere else. This blogger is especially fond of the City of Heroes 'alakazamreact' emote that lets you turn into a pumpkin temporatily. (It used to be indefinite, but the rumor is that people were using their pumpkinhood as an ambush technique in PvP, so it got nerfed.)

What are your favorite emotes from the MMOs you play? Are there any that really ought to be included, but aren't yet?
