Since his entry into the national political landscape, most of us have been wondering when will the ultra smooth, never ruffled President Barack Obama lose his cool? Well, Saturday Night Live and Dwayne Johnson (“The Rock”) answer this question for us in a recent skit.  A staffer prods President Obama to get angry with Republican Senators who oppose his bills. After a round of questions peppered with baby insults, Obama finally gets mad (in a “Hulk-like” fashion). So now people know… when Barack Obama becomes angry — he really turns into the “Rock Obama.” Check out the video.
