Unauthorized images like that are generally not anything a sports team such as the Blazers could make happen, due to the copyright issues. I suppose it's possible the Blazers could make a deal with FOX for the Simpsons likeness, but it seems unlikely.
But FOX is the right-holder. Is FOX from Portland? Does FOX have the necessary sentimentality? These are good questions to be answered.
This is all I have to wear to get on Fox' Ten Most Wanted show? Then the Fox Network will track me down and bust me? And it'll be on Fox News and Sean Hannity will hate me? This is like a dream come true!!
