I was looking for the video while you replied. Did you notice that HuffPo deleted the video r7eferred to in its article? The pertinent part, where he threw a snit that a tween could be proud of, has been erased.
Do we remember when he was complaining that the interwebz could not be cleansed to his satisfaction, and he wanted to know WHY he couldn't sanitize and rearrange search results to his satisdaction? This is the caliber of ego he revealed.
Rachel was on Air Anerica at the time, not a colleague but absolutely a peer. Why should she be expected to overlook a slam intended to demean her professional abilities? Let's compare her "gets" (and her audience) to those of MJ, shall we?
This earlier portion where he is merely snide and condescending ahead of his snit survived the purge:
Why would you assume that Rachel is the one holding a grudge, LOL?
