immoralilly wrote this awesome fic containing Sam, Dean, The Castle Anthrax, and Spanking. It contains some of the most hilarious dialogue yet known to man and a discussion of the historicalness of boobs. Also, Dean's great retort to the Knights who say Ni is "My brother is taller than you." *sporfles*
All of you must read it at once. Go now if you call yourself Monty Python fans or HUMANS.
