LOL at this thread first of all, but honestly, Skip has been prodded to be the way he is now. I remember the Cold Pizza days when it was just him and Woody, and he was extremely subdued by comparison.
But the power behind the scenes at First Take have more than likely encouraged his behavior and also the usage of social media, which is why they have a new Hashtag "something" damn near everyday. I like the banter between him and Stephen A, I think it's entertainment more than anything else, but even when Skip has some ground to stand on (he definitely was first on Lebron way back in '07, the Spurs this year, and some of Tebow's improbable crap) he just grinds it down your throat in such a relentless way that it almost makes Stephen A necessary to retort with the same level of brashness.
