I'm going to AX this week, but the chance of 
winning a sketch there is really based on pure 
luck.  If you have been there, you should know 
how tough to win the sketch from its lottery 
system.  Only 10 lucky winners out from 300 to 
500 people from his panel.  Plus the AX staffs 
are so strict nowaday, it's so hard just to get 
close and chat with the guests.  I wish to win 
one for myself though...
