Cent One: Rosencarl and Guildernlenny is far and away the funniest joke I've heard all week. I have no clue why. I just think the names are hilarious, and I laughed for a stragiht minute.
Cent Two: The River Styx would have been funnier if they were playing come sail away.
P.S. I liked the Ghostbusters ending. It was silly and stupid, but I thought that was a funny juxtaposition - a stupid capper to an otherwise very literate show.
