Chael does it for cold hard cash, Jones does it because he wants to be loved. Well, one is more pathetic, but both are fakers
But everyone knows what Chael is doing (Well not everyone). Part of his shtick is saying stuff that is obviously a lie or wrong and saying it with a straight face as it it were the truth. That has become basically his signature move. Some find it funny some dont but everyone knows he is just messing around. He knows that everyone knows the stuff he says is a lie and yet he says it. It usually has me lol
What Jones does is like partly disturbing. He isnt joking by any means. He lies just because he wants to have a good image. And its a really disgusting trait. Surprisingly when he dropped Machida on the face after he choked him out i was thinking "Well finally he is acting like himself" and then right after its back to the fake good image nonsense "Hey go check on him to gain fans".
Not to mention he used to snitch on people smoking pot during highschool.
