why do the judges stand up and applaud with all the guests half the time they are no better than the contestants ????

becuz its the polite thing to do...

I agree, Alicia Keys was awful. She did one good thing though.............she shut up the stupid audience, they only woke up when they realised that she was almost done.

Well Gary isn't very polite to Rylan is he ? Rylan isn't that much worse than Alicia Keys in my opinion
