I saw the best of Will Ferral this skit is also found on Saturday Night Live: 101 Most Unforgettable Moments I was unable to find a comlete video of it but it looks like wikipedia has a synopse reading it is almost as funny for thoes of you that listen to bob and tom show then you will know they also have a skit of songs with cowbells anyway The Truth Behind the cowbell is listed at the end of the article hehee
