// Output:
//
// I'm back and I'm ringin' the bell
// A rockin' on the mike while the fly girls yell
// In ecstasy in the back of me
// Well that's my DJ Deshay cuttin' all them Z's
// Hittin' hard and the girlies goin' crazy
// Vanilla's on the mike, man I'm not lazy.
//
// I'm lettin' my drug kick in
// It controls my mouth and I begin
// To just let it flow, let my concepts go
// My posse's to the side yellin', Go Vanilla Go!
//
// Smooth 'cause that's the way I will be
// And if you don't give a damn, then
// Why you starin' at me
// So get off 'cause I control the stage
// There's no dissin' allowed
// I'm in my own phase
// The girlies sa y they love me and that is ok
// And I can dance better than any kid n' play
//
// Stage 2 -- Yea the one ya' wanna listen to
// It's off my head so let the beat play through
// So I can funk it up and make it sound good
// 1-2-3 Yo -- Knock on some wood
// For good luck, I like my rhymes atrocious
// Supercalafragilisticexpialidocious
// I'm an effect and that you can bet
// I can take a fly girl and make her wet.
//
// I'm like Samson -- Samson to Delilah
// There's no denyin', You can try to hang
// But you'll keep tryin' to get my style
// Over and over, practice makes perfect
// But not if you're a loafer.
//
// You'll get nowhere, no place, no time, no girls
// Soon -- Oh my God, homebody, you probably eat
// Spaghetti with a spoon! Come on and say it!
//
// VIP. Vanilla Ice yep, yep, I'm comin' hard like a rhino
// Intoxicating so you stagger like a wino
// So punks stop trying and girl stop cryin'
// Vanilla Ice is sellin' and you people are buyin'
// 'Cause why the freaks are jockin' like Crazy Glue
// Movin' and groovin' trying to sing along
// All through the ghetto groovin' this here song
// Now you're amazed by the VIP posse.
//
// Steppin' so hard like a German Nazi
// Startled by the bases hittin' ground
// There's no trippin' on mine, I'm just gettin' down
// Sparkamatic, I'm hangin' tight like a fanatic
// You trapped me once and I thought that
// You might have it
// So step down and lend me your ear
// '89 in my time! You, '90 is my year.
//
// You're weakenin' fast, YO! and I can tell it
// Your body's gettin' hot, so, so I can smell it
// So don't be mad and don't be sad
// 'Cause the lyrics belong to ICE, You can call me Dad
// You're pitchin' a fit, so step back and endure
// Let the witch doctor, Ice, do the dance to cure
// So come up close and don't be square
// You wanna battle me -- Anytime, anywhere
//
// You thought that I was weak, Boy, you're dead wrong
// So come on, everybody and sing this song
//
// Say -- Play that funky music Say, go white boy, go white boy go
// play that funky music Go white boy, go white boy, go
// Lay down and boogie and play that funky music till you die.
//
// Play that funky music Come on, Come on, let me hear
// Play that funky music white boy you say it, say it
// Play that funky music A little louder now
// Play that funky music, white boy Come on, Come on, Come on
// Play that funky music
