Xerxes: Hmm. Interesting.
Xerxes: Oh, I was just reading about some of my memorable events.
Servant: Oh yes! Thrilling reading indeed sire.
Xerxes: Yes, yes, yes, but I have come upon something of a mystery... Do you remember that plot to assasinate me by those two dimwits... uh Bigthan and Terish?
Servant: Yes my leige. Tsk, tsk, tsk. What fools they were to try to harm the ruler of the earth, the monarch of all...
Xerxes: Oh, nevermind the blather it says here that Mordecai exposed the plot.
Servant: Oh yes sire. That is true.
Xerxes: But it doesn't list his reward.
Servant: Uh.. reward?
Xerxes: Yes (Imitatingly) Reward. Well don't you think the man deserves something for saving me?
Servant: I know not of others, but as for me, my reward would be the knowledge that your majesty is safe.
Xerxes: Well that's all well and good but you never saved me, this man did! Now stop the flattery you fool and tell me what reward he recieved!
Servant: (Gulp) Uh, Heh, Heh, Heh, I don't know your majesty.
Xerxes: (Imitatingly) You don't know your majesty, Well find out!
