1) They're an act. They're together. The one juggler had a partner that messed up and he didn't make it. So the harmonica's bro isn't that good, but they make it.
2) Re-read reply #9. I said judging-wise, not personality. I don't care about either of their personalities. It just seems like out of the 3 judges, there is one that would take everybody to the finals (Brandy, but not last night) one that is SOOOOOOO hard to please (Pier), and the one in-the-middle guy that doesn't have one of those obvious characteristics, and who's left? David and Randy. And they seem to neatly fit that category.
Anyway, last night was weird. I missed the results show last week and the judges won't decide until today, so urgh... although I liked the dangerous comic guy, Brandy was funny during that.
