YouTube user marioboy22601 remixed Will Smith's famous introduction to The Fresh Prince of Bel-Air with the theme music of Thomas and Friends. It totally works! Thomas definitely should leave the mean tracks of Philly for a safer environment on Sodor.
I found this video at Boing Boing, which has links to other Thomas and Friends re-mixes, including the music of Biggie Smalls, Cypress Hill, and AC/DC.
