I mean really, do you even need an explanation? You do? Well OK, here it is from the lips (or fingers) of Al himself:
"This is me on a Japanese TV show in 1984, singing 'Eat It' (badly) in half-English, half-phonetic-Japanese. My look of confusion is not an act - I have absolutely no idea what is going on here. The clip features dancing Sumo wrestlers, a Japanese Michael Jackson, and of course, a guy dressed up as a giant lobster."
Get ready to have your mind blown after the jump.
