These guys never cease to make me laugh out loud but the audio quality on this performance was inexcusably poor - it was as though all the sound came from a mic placed in the crowd at the back of the room. The parts that I could hear were funny, but unfortunately they were few and far between.
Also, the gag that ran during the credits was of extremely bad taste... the laughter came to an abrupt halt and everybody just looked at each wondering where what we had just witnessed had come from. If you must see this, don't watch the credits!
Also, Weird Al is great but his involvement was minimal.
