  I seen you jockin J.C. cause he got a Mercedes
  and you know about his ladies, and all his babies
  You just wanna ride, and get inside
  and run around town, like Bonnie'n'Clyde
  But see the moves you're makin, the route you're takin
  will lead to heartbreakin and I'm not mistaken
  You like his money, you'll be his honey
  Get the truth - no excuse - you're a great big dummy!
  DUMB GIRL.. DUMB GIRL!
    [D.M.C.]
  I wish I knew, why a girl like you
  wants to do all the things that you do
  I know you want a man, but you should understand
  that J.C. ain't D, you shouldn't be his fan
  You're not this fine, you're out of your mind
  And I wrote this rhyme just for your kind
  Don't be misled, remember what I said
  The rhymes of rappers surely knock some sense in your head
  DUMB GIRL.. DUMB GIRL!
    [Run]
  (NOW..) Now you're the flyest girl, in the whole school
  but they don't call you fly - they call you fool
  Because you don't go to class, you will not pass
  You like to go but you should slow because you're goin too fast
  And I can tell that you're dumb when you walk in the place
  Walkin round with your thumb cold stuck in your face
  Always sinnin never winnin cause you're last in the race
  You get high and tell a lie and think that makes you the ace
  DUMB GIRL.. (stupid!) THE GIRL IS..
    [Run]
  Now you're a stupid sex fiend, with no will power (POWER)
  Hit four guys in the bathroom at your last baby shower
    [D.M.C.]
  All the guys call you fast (FAST) but I call you slow (SLOW)
  Always sniffin or givin (GIVIN) somebody a blow (BLOW)
  Givin every guy a try (TRY) at the wink of an eye (EYE)
  There's somethin that you're missin, that money can't buy (BUY)
  When it comes to love, you're even hated by Cupid (CUPID)
  You're (silly) dilly (dumb) and you're JUST PLAIN STUPID!
  DUMB GIRL.. (stupid!) DUMB GIRL!
    .. the girl is ..
    [D.M.C.]
  I hope you to listen to the words, that I speak
  I'm not playin, what I'm sayin, can never be weak
  You should use your brain, but you don't have one
  And when it comes to sense you don't have none
  YO YO you should know where I'm comin from
  But you're just dumb (diddy) dumb (diddy diddy) DUMB DUMB!
    [D] DUMB GIRL!
  [R] Dumb with a capital D!
  [D] DUMB GIRL!
  [R] Stupid as can be, BREAKDOWN!
    .. the girl is ..
    DUMB GIRL! DUMB GIRL!
  .. the girl is dumb!
