Ok here's one I heard a while back . .
There's a Galka, Hume, Taru and Elvaan standing on the top of a very high cliff. They are all discussing who is the better race when the Galka shouts out
"My race is the best, I love my race and I shall prove it by throwing myself off this cliff!"
He runs towards the edge crying "For Galkans everywhere!" and leaps off in an act of noble sacrifice.
The Hume, never to be outdone by a Galka, does the same shouting "For the Humans!" and leaping to his doom.
The Taru and Elvaan look at each other. Well, they won't be outdone by the other classes, so the Elvaan takes a quick look around and shouts "For the Elvaans!" and punts the Taru off the cliff.
Edit: just copied the joke from a really old post of mine.
