I THINK YOU ARE ON TO SOMETHING!! WOW!... wait...is that steve puppeteering? it sure looks like him...but ive never seen him with glasses? if not then we may have a clue as to who is puppeting constantine!!
It's quite simple. You see, Kermit isn't Kermit, but he is still is Kermit. Meanwhile, Constaine is Kermit half the time, and Miss Piggy is Tina Fey. But Fey is actually Gervais who is also Miss Piggy. All the while, Gonzo is Charles Dickens, and that tiny little mole is actually Robin.
But seriously, I just thought of something. What if (emphasis on "what if") the mole is Kermit's way of hiding from the press? That would make the huge bunch of flowers that he's hiding behind logical. What if the press were duped into thinking that this guy isn't really Kermit (despite the fact that all he did was put a mole on his face)? Kind of like the Chicken Boo cartoons. Almost nobody thinks that Chicken Boo is a giant chicken, ebven though it's extremely obvious.
