This has to be the absolutely funniest site on the world wide web...

What is does is it takes an MP3 of a midi file of the background of a song (the music w/o lyrics) and goes to the various dictionary.com like sites which have pronunciation guides for words, takes each word that the dictionary pronounces for each word of the lyrics, and brings it, in beat to the music, and melds it with the MP3 background.  These are absolutely hilarious!!!  Verbatim pronunciations in various inflections, mistaken inflections, the comedy potential is endless!!!
