I just saw that video for the first time a few days ago, I thought it was old. But yeah, noticed Theotis as well.
What's the fucking deal with Big Sean though? If there is anything good in any of his songs (that I've heard) it's the feats and beats at most. I wondered this after I saw his name on some list for best rappers 2011.
*edit. Oh yeah, and his flow is like he's reading a bedtime story.
