I caught them on-demand earlier (and the last two are great). But the GOOD news is HBO picked the show up for a second season, so they'll bring back the on-demand episodes closer to the second season premier. They did that with Flight of the Conchords at least, so people had a chance to catch up.
On a side note - Six episodes sucks as a "season". Hopefully there'll be a lot more in the second. HBO, whatever needs to be set up to make that happen - set that @%$# up!
