Because it's in the context of a boxing match he had no business fighting in.
I also don't care if Snoop decides to light someone up because of their cooking abilities.
That last line is an interesting one.
At first I was going to say "good point", because not to contradict myself but since I don't cook much and lack skills in that area, if Snoop was to knock someone in the same fashion as he did DC/Conor for their cooking skills or lack there of, I wouldn't be offended and just laugh.
But then I look at that scenario, and #1 I am more than likely not going to be watching a cooking show regardless if Snoop is on it if I'm not into cooking, and #2 even if I was to watch the show, if Snoop is making fun of one of the chefs, I do not see in any way how that is going to promote or encourage me to cook whatever they are cooking on that show.
So, again I just don't see what Snoop is doing beneficial for UFC by the commentary he is doing.
