This is meant to be entertaining, and how boring would it have been if we had 4 contestants who behaved like Tupele?. She was very nice, but hardly contributed anything to the show. The other 3 were good fun and entered into the spirit, providing amusement for the viewer. Most of the time she was totally out of step with what was going on and it was hard to see why she bothered. Agreed Ken was a bit OTT but that was presumably why he was included.
