If you're playing around with Emotes in an MMORPG you, almost by definition, have nothing better to do. But they can be occasionally useful, and at least fun to try out when you're waiting for a guildmate or something. The Elder Scrolls Online has 172 for you to try.
Here's a look at some of the more fun ones from IGN. Bonus points for featuring a kitty, uh, I mean Khajiit.
If you want to check out the Emotes in animated form, there's a huge list here:
