Warcraft - A Quest you have to do

No, I don't mean that every player is forced to do this quest by the game.  I mean that you are doing yourself a great injustice if you do not do this quest.  It is given by the following NPC at the Southpoint Gate in Hillsbrad.

This is possibly the funniest quest that I have done in the 6 years that I have been playing World of Warcraft.

And because I do not want to spoil the quest for you, so hints on what it pertains to except it makes fun of stereotypes.
