"I am the walrus" by John Lennon, reincarnated as Jim Carrey

So many questions. When did Jim Carrey learn how to sing? Why was this video made? Why did they get so sloppy with the dubbing toward the end? Who paid for the symphony? Why wasn't this a chart-topping best seller? Who's the dude with the toilet bowl bal dude?

I'm guessing this is around his Ace Ventura phase (the first one, of course). You can hear it coming through every so often.
