The guy goes overboard sometimes, but it's understandable. Sielu's observation was so good, they still stick to his routine. But he was also respectful, had some serious topics, like nearly dying during his Tatau, or the actual dangers of climbing a tree. You could feel his actual anxieties and worries behind every joke. And that cannot be copied.
Get off his case, his not the only one doing this. Very rehearsed ... he more than likely does it several times a day, its light entertainment. Who did Chief Sielu copy or was he the original?
