I'm sorry I told you those pants made your ass look fat
  oops my bad
  I'm sorry I tried to borrow condoms from your dad
  oops my bad
  I called you by your best freind's name
  when you and I were fooling around and around
  Then I went and made out with that same best friend
  the weekend you left town
  Oops my bad
  It's all my, it's all my fault
  I never should have let those little things ruin what we had
  Oops my bad
  I'm sorry I made out with you younger sister
  Oops my bad
  I swear I thought it was you when I kissed her
  you look so similar
  Oops my bad
  Now seems a good a time as any for apologies
  I'm sorry I never told you about my STDs
  I've got herpes, so do you now
  And your best friend, and your sister
  And your mom and I suppose even you dad
  Oops my bad
