First video; I aggree, the instructor should be kicked where the sun don't shine; 1) because he let her do something THAT dangerous (no matter how unknowingly on her part) to everyone there, herself included... and 2) he didn't take the opportunity to grab hold of that hotty (rrrruff!!!) to correct the situation!!
Second video: obviously fake... but makes a great (and funny) point about the "street cred" culture in the gun world today (I.E. "IDIOTS").
Third video; Can't hate this on just one level!! I want to beat the crap out of him for his fashion mistakes alone!!! Showed that one to my son (who's 10 and a shooter...with me in attendence of course) All he could say was "Moron.... probably wind up shooting himself in the junk!!" .... One can only hope, son... One can only hope.
