I'm losing my hair
  and my vision is shady
  Last night I dreamt
  of an over weight lady
    But I need a young thang
  to keep up with my pace
  to hold me in her arms
  and take me straight to second base.
    I know my calculus
  it says u + me = us
  Sing it Chad for me
  I know my calculus
  it says u + me = us
    Oh yeah, calculus...
    Yeah, we're 2gether, we're 2gether
    [Rap:]
  Girl, algebra, trigonometry
  can never equal up to what you do to me
  so, let's integrate
  don't differentiate
  If you were in my class
  there's ain't no way I could pass I hate english, gym
  & not to mention
  I can't even afford to pay my attention
  (can't pay my attention)
  not even philosophy can ever come between us
  but we will always have our calculus.
    I know my calculus
  it says u + me = us
  I know my calculus
  it says u + me = us
    Calculus, calculus
  Go go go go go
  Ooh baby, oh lord
  U + me = us
    Well I've never been good at history
  & I don't give a crap about Robert E. Lee
  When it comes to cosines, I know a thing or 2
  & I kicked ass on the test about me & you
    I know my calculus
  it says u + me = us
  I know my calculus
  it says u + me = us
    U, plus sign, me, equal sign, us
  U, plus sign, me, equal sign, us
  U, plus sign, me, equal sign, us
    Oooh
  Girl, no subject comes close to you
  2gether, sing it
    I know my calculus
    I know my calculus
  it says u + me = us
  Say I know my calculus
  it says u + me = us
    Calculus
