This online version of karaoke sounds sort of like Stephen Hawking covering Dr. Dre. Listen up,

You've heard of karaoke, the art of singing lyrics to popular songs, usually in taverns, while the music plays in the background. Dictionaraoke is an online version that features parodies of popular songs using karaoke-style backing music with vocals provided by audio pronunciation samples from online dictionaries. Typically, the voice functionality comes from Merriam-Webster's or Microsoft Encarta.

All of the music sounds somewhat Stephen Hawkingesque, but listening to Merriam-Webster's do a cover of Dr. Dre's "Nuthin' But a 'G' Thang" (featuring Snoop Doggy Dogg) is somehow exhilarating.
