Donald Trump s biggest claim to fame, The Apprentice and Celebrity Apprentice, were endangered last year when he revealed himself to be nothing but a horrible, childish bigot in presidential candidates  clothing. At that time, NBC fired him and began looking at who might replace him, and now they have their answer, along with a very insulting tagline.NBC tapped Arnold Schwarzenegger to replace Trump last fall, but made it official with a new promo they released over the weekend. It says, on The Apprentice s YouTube channel: Brains, brawn and business acumen   we re building a better boss.  [emphasis mine]Ouch. That can be taken several different ways   the most obvious being that they think Schwarzenegger s more rounded personality is a better fit than Trump ever was.That s insulting enough. However, NBC specifically fired Trump over his comments about Mexican immigrants last year, at the same time other companies cut ties with him for the same reason. So this could also be seen as a dig at him for what s proven to be his severe lack of even a modicum of professionalism pretty much anywhere.NBC also won t bring Trump back, even if he loses the election and comes crawling back on his hands and knees. NBC s entertainment chair, Robert Greenblatt, said earlier this month: No. He would never be back on  Celebrity Apprentice,  as long as I m here. Woe to Trump if whatever new business ventures on which he embarks after losing in November fail, just like so many of his other businesses have failed.Rumors are swirling that Trump may be using this election cycle to help launch his own television network, rather than making a serious run at the White House. However, Trump Steaks, Trump Vodka, Trump University, Trump Taj Mahal, and more, were all such dismal failures it s a wonder Trump thinks he can even pull off a new business venture. Despite possibly having help from Roger Ailes and Steve Bannon, a Trump television network might fail just as hard.Oh, Trumplestiltskin. His days of fame are numbered, and NBC is trying to make that number shrink. Watch the promo for  Celebrity Apprentice  below:Featured image via screen capture from embedded video
