I wouuld say that magician guy has been the most interesting so far. I usually take pride in my ability to figure out the tricks these guys employ, but I'm lost with him.
I thought that David & Leeman should have gone through based on my opinion that their act was bigger, and made for "a big stage." I have no idea how the hell he does it as well, but meh. Also, the dancers will be splitting around 50k if they win lol.
