I almost didn't play it, because of the intro picture, but while not especially good, it's not as bad as Antares' and Critter's reaction suggests.
I was reacting to his statement that went along with it that said The Simpsons have never done a musical number to match any in Family Guy.
And none of those shows are anywhere near as good as Futurama. It really bugs me that Fox brought back Family Guy but didn't Futurama. At least Comedy Central started showing new episodes.
In my estimation this is Sheen's finest performance.
