I know that I have declared Piff the Magic Dragon the winner of America's Got Talent for 2015, but I figured out who's going to be in the finals with him, and that's Oz the Mentalist!

I don't have a clue how he was able to get inside Howie Mandel's and Howard Stern's heads, but boy did he! If you figure out how he did this, let me know!

America's Got Talent is on NBC Tuesday and Wednesday nights at 8 PM in the summer.
