I've been thinking about my mate's girlfriend
  In a way I shouldn't be
  Wondering 'bout the way she'd look
  Posing like they do in books
  Wearing very little, except maybe a grin
  I could bring a bottle her boyfriend I could throttle
  And while he's out the way I can jump right in
  'Cause
    Wish that I was sleeping with my best mate's girlfriend
  I don't wanna go
  She want's me to stay
  But, my mate is getting in the way
    If he'd should go out to the kitchen
  That would give me time just to get a kiss in
  If he should go to the garage instead
  Well that'll give me time to get her into bed
  Do it on the double or we'll get into trouble
  And he'll make a punching bag outta my head
    I'm sure that I've seen her winking
  And I'm sure she's thinking what I'm thinking
  I'd sure like to get to know her better
  Especially what lies beneath that sweater
  Fed up of thinking about it in dreams
  I wanna know what really lies beneath your jeans
