Did anyone go to Flight of the Conchords?

I just read the review of Flight of the Conchords show at the Northrop and I kind of wish that I would have went! I have only seen a few of the shows and they are obviously very funny, but I read that they came out in cardboard robot heads on Sunday night - how hilarious would that have been to see!?
In case you are not sure, Flight of the Conchords, is the show on HBO that has a cult following of epic proportions. When they were here last year, the show at the Orpheum sold out in minutes and there was not a ticket to be found. This time around they played at the Northrop which holds over 4000, but even still Northrop Auditorium tickets for this show were a very difficult find. The show was completely sold out!

If anyone went I would love to hear a review of the show!
