It is amazing, isn't it?
The producers of the show have everyone go through some preliminary rounds before they stand in front of Simon, Paula and Randy.
So those weird people actually got through because they were so awful. :-/
I cannot believe they let the crazy dude through to Hollywood. I would have preferred the Ukranian chick who rolled around on the floor to Bohemian Rhapsody. :-D
Yah, well, clearly they like having some train wrecks for us to rubberneck... keeps things compelling... :-)
