That was an extremely entertaining episode. One of the best TCs ever (from an entertainment standpoint).
As for the Reward Challenge, there might have actually been one, but when the producers saw the pure-gold in the TC, they just decided not to show it.
Then again, as a person on the tribe, would you really go around making sure everyone could spell your name, just so they could write it down when voting?
If it was me, I might tell them that my name is actually spelled like one other people.
