Hey guys, here's the problem.  There's this calender in my movie that i made for work that shows girls in bikinis...the boss says i need to get rid of that...how can i get that blur over the calender, like they have in COPS or music videos on people's shirts or hats with logos they can't use.  I want to blur out the calender.  It will look funny.  Help
