Woops, put this in wrong thread a few minutes ago (was trying to get info out fast):
I just got two tickets for Jon Stewart. There are currently one available Monday, one Tuesday, one Wednesday and seven on Thursday.
http://www.thedailyshow.com/ticketsFive minutes later: Okay, gone now, but they have a running tally of ticket availability for each day, so it's really easy to see/deal with. I'd suggest going back and checking each day, maybe around noon or 1 since there were tix available that time today?
