+// 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
